Deep neural networks (DNNs) have greatly advanced the frontier of image super-resolution research and replaced traditional methods as the de facto standard approach. The attention mechanism enables the SR algorithms to achieve breakthrough performance after another. However, limited research has been conducted on the interaction and integration of attention mechanisms across different dimensions. To tackle this issue, in this paper, we propose a cross-dimensional attention fusion network (CAFN) to effectively achieve cross-dimensional inter-action with long-range dependencies. Specifically, the proposed approach involves the utilization of a cross-dimensional aggrega-tion module (CAM) to effectively capture contextual information by integrating both spatial and channel importance maps. The design of information fusion module (IFM) in CAM serves as a bridge for parallel dual-attention information fusion. In addition, a novel memory-adaptive multi-stage (MAMS) training method is proposed. We perform warm-start retraining with the same setting as the previous stage, without increasing memory consumption. If the memory is sufficient, we finetune the model with a larger patch size after the warm-start. The experimental results definitively demonstrate the superior performance of our cross-dimensional attention fusion network and training strategy compared to state-of-the-art (SOTA) methods, as evidenced by both quantitative and qualitative metrics.","PeriodicalId":13159,"journal":{"name":"IEEE Transactions on Broadcasting","volume":"70 3","pages":"909-923"},"PeriodicalIF":3.2,"publicationDate":"2024-06-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141510396","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, evaluating the perceptual quality of an impaired video in the absence of the original reference signal remains a significant challenge. To address this problem, we propose a novel No-Reference (NR) video quality metric called NR-VMAF. Our method is designed to replicate the popular Full-Reference (FR) metric VMAF in scenarios where the reference signal is unavailable or impractical to obtain. Like its FR counterpart, NR-VMAF is tailored specifically for measuring video quality in the presence of compression and scaling artifacts. The proposed model utilizes a deep convolutional neural network to extract quality-aware features from the pixel information of the distorted video, thereby eliminating the need for manual feature engineering. By adopting a patch-based approach, we are able to process high-resolution video data without any information loss. While the current model is trained solely on H.265/HEVC videos, its performance is verified on subjective datasets containing mainly H.264/AVC content. We demonstrate that NR-VMAF outperforms current state-of-the-art NR metrics while achieving a prediction accuracy that is comparable to VMAF and other FR metrics. Based on this strong performance, we believe that NR-VMAF is a viable approach to efficient and reliable No-Reference video quality assessment.","PeriodicalId":13159,"journal":{"name":"IEEE Transactions on Broadcasting","volume":"70 3","pages":"844-861"},"PeriodicalIF":3.2,"publicationDate":"2024-06-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141940837","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The existing Super Resolution (SR) methods generally design powerful networks to compensate the loss information introduced by down-sampling. But the information of entire video is not fully utilized and effectively fused, resulting in the learned context information that is not enough for the high quality reconstruction. We propose a multi high-quality frames Referenced Cross-scale compressed Video Super Resolution method (RCVSR) that wisely uses past-and-future information, to pursue higher compression efficiency. Specifically, a joint reference motion alignment module is proposed. Low resolution (LR) frame after up-sampling is separately aligned with past-and-future reference frames to preserve more spatial details; at the same time this LR frame is aligned with neighborhood frames to get continuous motion information and similar contents. Then, a reference based refinement module is applied to compensate motion and lost texture details by computing similarity matrix across channel dimensions. Finally, an attention guided dual-branch residual module is employed to enhance the reconstructed result concurrently. Compared with the HEVC anchor, the average gain of Bjontegaard Delta Rate (BD-Rate) under the Low-Delay-P (LDP) setting is 24.86%. In addition, an experimental comparison is made with the advanced SR methods and compressed video quality enhancement (VQE) methods, and the superior efficiency and generalization of the proposed algorithm are further reported.","PeriodicalId":13159,"journal":{"name":"IEEE Transactions on Broadcasting","volume":"70 3","pages":"895-908"},"PeriodicalIF":3.2,"publicationDate":"2024-06-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141940838","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Whereas many current compander designs assume a parametric model for the form of the transformed Rayleigh amplitude distribution, we define a constrained optimization problem for the functional form of the transformed distribution. We determine an optimal distribution which minimally deviates from the Rayleigh distribution and use a Sobolev norm to quantify distance. Use of the Sobolev norm imposes smoothness constraints on the transformed distribution, which are associated with lower out-of-band interference levels. We incorporate Lagrange multipliers into the problem formulation to enforce the constant power and probability density function constraints. We solve the constrained optimization problem using techniques from the Calculus of Variations and discuss compander and decompander design. We investigate the effect of incorporating derivative information, into the optimization formulation, on compander performance. We demonstrate compander performance through numerical simulation and compare compander performance to performance from a state-of-the-art variational compander which does not use derivative information in the formulation. We demonstrate performance improvements in out-of-band power rejection using the new compander.","PeriodicalId":13159,"journal":{"name":"IEEE Transactions on Broadcasting","volume":"70 3","pages":"955-962"},"PeriodicalIF":3.2,"publicationDate":"2024-06-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141940840","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In particular, we propose a novel IM-based channel estimation algorithm for FTN signaling HF communications including pilot sequence placement (PSP) and pilot sequence location identification (PSLI) algorithms. At the transmitter, we propose the PSP algorithm that utilizes the locations of pilot sequences to carry additional information bits, thereby improving the SE of HF communications. HF channels have two non-zero independent fading paths with specific fixed delay spread and frequency spread characteristics as outlined in the Union Radio communication Sector (ITU-R) F.1487 and F.520. Having said that, based on the aforementioned properties of the HF channels and the favorable auto-correlation characteristics of the optimal pilot sequence, we propose a novel PSLI algorithm that effectively identifies the pilot sequence location within a given frame at the receiver. This is achieved by showing that the square of the absolute value of the cross-correlation between the received symbols and the pilot sequence consists of a scaled version of the square of the absolute value of the auto-correlation of the pilot sequence weighted by the gain of the corresponding HF channel path. Simulation results show very low pilot sequence location identification errors for HF channels. Our simulation results show a 6 dB improvement in the MSE of the channel estimation as well as about 3.5 dB BER improvement of FTN signaling along with an enhancement in SE compared to the method in Ishihara and Sugiura (2017). We also achieved an enhancement in SE compared to the work in Keykhosravi and Bedeer (2023) while maintaining comparable MSE of the channel estimation and BER performance.","PeriodicalId":13159,"journal":{"name":"IEEE Transactions on Broadcasting","volume":"70 3","pages":"774-791"},"PeriodicalIF":3.2,"publicationDate":"2024-06-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141940845","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Among them, mmWave spectrum exploitation stands out for its ability to deliver ultra-high data rates. However, its full adoption beyond fifth generation multicast systems (5G+/6G) remains hampered, mainly due to mobility robustness issues. In this work, we propose a solution to address the problem of efficient sidelink-assisted multicasting in mobile multimode systems, specifically by considering the possibility of jointly utilizing sidelink/device-to-device (D2D), unicast, and multicast transmissions to improve service delivery. To overcome the complexity problem in finding the optimal solution for user-mode binding, we introduce a pre-optimization step called multicast group formation (MGF). Through a clustering technique based on unsupervised machine learning, MGF allows to reduce the complexity of solving the sidelink-assisted multiple modes mmWave (SA3M) problem. A detailed analysis of the impact of various system parameters on performance is conducted, and numerical evidence of the complexity/performance trade-off and its dependence on mobility patterns and user distribution is provided. Particularly, our proposed solution achieves a network throughput improvement of up to 32% over state-of-the-art schemes while ensuring the lowest computational time. Finally, the results demonstrate that an effective balance between power consumption and latency can be achieved through appropriate adjustments of transmit power and bandwidth.","PeriodicalId":13159,"journal":{"name":"IEEE Transactions on Broadcasting","volume":"70 3","pages":"1076-1090"},"PeriodicalIF":3.2,"publicationDate":"2024-04-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=10513425","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140839613","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
