Zou, Yangzhen Zhao, Liansheng He, Shuai Han","doi":"10.1109/BMSB58369.2023.10211212","DOIUrl":"https://doi.org/10.1109/BMSB58369.2023.10211212","url":null,"abstract":"Satellite transmission technology is developing rapidly, and based on the satellite system's broadcast transmission ability, the satellite system's navigation and communication ability has become a hot topic of future development. In earlier research, our team proposed a satellite navigation and communication integrated technology based on spread spectrum broadband signals. The technology can significantly increase the GNSS satellite downlink broadcast rate while ensuring downward compatibility. This paper summarizes the technology and its technical system. The proposed broadcast signal consists of the navigation signal and communication signal. The navigation signal part is precisely the same as the existing GNSS signal and provides the synchronous service for the communication signal based on the original positioning service. Cyclic Code Shift Keying (CCSK) modulation is used for the communication signal. PN codes in the same family as the navigation signal are used for the spread spectrum. The communication and navigation signals are in the same frequency and phase on radio frequency and synchronized on the baseband. In order to avoid the degradation of detection performance and error performance caused by cross-correlation interference between navigation and communication signals, the code phase optimization algorithm is introduced to turn the cross-correlation function into a favorable condition and enhance the detection performance of the pilot channel and communication channel. Because of the discontinuity of the code phase set, the receiver of the signal can use the fuzzy decision algorithm to improve the fault tolerance of the system to phase jitter and synchronization deviation. Because the proposed signal system transmits information by adjusting the signal delay, the signal is susceptible to the multipath effect. To solve this problem, we design the master-slave Rake receiver strategy by taking advantage of the characteristics of the pilot and communication signal in the same frequency and phase. The Rake receiver parameters are determined through the pilot channel and applied to the communication channel. This method has little change to the receiver and can effectively compensate for the multipath effect. It does not need to occupy more frequency points in the spectrum resources and has good compatibility, which is conducive to promoting and utilizing existing GNSS equipment.","PeriodicalId":13080,"journal":{"name":"IEEE international Symposium on Broadband Multimedia Systems and Broadcasting","volume":"84 1","pages":"1-5"},"PeriodicalIF":0.0,"publicationDate":"2023-06-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83891726","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The majority of current federated learning systems are oriented for single task while participants in the Internet of Vehicles (IoV) demand to train different models for multiple intelligent services simultaneously. As one of transfer learning methods, multi-task learning (MTL) has the potential to integrate with federated learning to realize personalized local training. However, the existing federated multi-task learning (FMTL) algorithms are faced with the problems of high implementation complexity and communication overhead. To solve the above issues, we propose a logical-cluster-based personalized federated multi-task learning framework named pFMTL. In the framework, the multi-task model is decomposed into a basic module for extracting features and K task-specific modules for outputting inferences. We leverage logical clusters and multi-task learning to enhance the personalization and generalization capability of task models, respectively. To improve the communication efficiency further, we also design a module-wise task scheduling strategy, which supports both user module scheduling and cluster aggregation scheduling to ensure the convergence of multi-task model with less communication overhead. Finally, the simulation results imply that pFMTL can increase task accuracy and reduce communication latency compared with other benchmarks.","PeriodicalId":13080,"journal":{"name":"IEEE international Symposium on Broadband Multimedia Systems and Broadcasting","volume":"1 1","pages":"1-6"},"PeriodicalIF":0.0,"publicationDate":"2023-06-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88805899","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A number of cutting-edge applications are predicted to be supported by 5G networks across the three categories: enhanced mobile broadband, ultra-reliable low latency communications, and enormous machine-type communications. The expectations and goals for the various services in the 5G networks have put a lot of pressure on mobile operators to maintain high Quality of Experience (QoE). The use of 5G Heterogeneous Networks (HetNets), which will provide consumers with the ability to be associated with either Macro Base Stations (MBS) or small cells, is one of the most promising solutions. Among the small cells, femtocells have drawn much attention recently. Yet, the most significant challenge with the deployment of femtocells is the high co-tier interference that can occur between different femtocell users. Artificial Intelligence (AI) and Machine Learning (ML)-based solutions are being incorporated in 5G networks to address this challenge. In this paper, we propose a ML Multi-Classification and Offloading Scheme (MLMCOS) to mitigate co-tier interference in 5G HetNets. MLMCOS classifies users into multiple classes based on their service priority along with their experienced co-tier interference. It then offloads some of them to the nearby Femto Base Stations (FBS) based on the availability of resources to ensure high QoE. ML classification algorithms are evaluated in terms of accuracy, recall, and precision. The performance of MLMCOS is then compared to those of Proportional Fair (PF) scheduling algorithm, Variable Radius and Proportional Fair scheduling (VR+PF) algorithm, and a Cognitive Approach (CA) in terms of Video Multimethod Assessment Fusion (VMAF), R-Factor, and RUM Speed Index (RUMSI).","PeriodicalId":13080,"journal":{"name":"IEEE international Symposium on Broadband Multimedia Systems and Broadcasting","volume":"15 1","pages":"1-6"},"PeriodicalIF":0.0,"publicationDate":"2023-06-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85930190","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Serverless edge computing (SEC) is a promising approach to effectively alleviate the shortage of MEC. However, existing research on SEC focus on the operating mode of the SEC server, they ignore the interaction between SEC and MU. To this end, we propose a Stackelberg game approach to maximize the utility of each MU. We present the model of the Stackelberg game and propose an iterative algorithm as the solution. We also consider the impact of the function resource pool and using renewable energy on SEC. In particular, when a function that required by a MU is not stored in this SEC, it downloads the function from could with extra cost. Meanwhile, the SEC has a lower cost by using harvested energy rather than purchasing from the grid. Simulation results show that the proposed scheme is efficient in terms of SEC’s profit and MU’s demand. Moreover, both MUs and SECs gain benefits from renewable energy.","PeriodicalId":13080,"journal":{"name":"IEEE international Symposium on Broadband Multimedia Systems and Broadcasting","volume":"20 1","pages":"1-7"},"PeriodicalIF":0.0,"publicationDate":"2023-06-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81425423","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
