How to achieve the quality of service (QoS) guaranteed traffic routing is always a research hotspot. However, due to the characteristics performed in the LEO satellite network, i.e., the four-link connection between the central satellite and its four adjacent satellites, connection switches caused by dynamic network topology, and different link rates between the same orbit and different orbits, the mainstream traffic routing methods will either cause the traffic congestion in the main stem, or the high computational complexity, which hinders their deployment and application in practice. To solve above problems, we propose a QoS guaranteed routing strategy, which assures the routing delay and link overhead of meeting engineering requirements. In this strategy, considering the above characteristics, we respectively propose the traffic priority division method, per hop QoS guaranteed technology and QoS guaranteed routing algorithm to guarantee differentiated traffic end-to-end QoS requirements. The simulation results show the superiority of our proposed method in terms of the lower delay, link cost, and computational complexity compared with existing literature.","PeriodicalId":201450,"journal":{"name":"2023 IEEE/CIC International Conference on Communications in China (ICCC Workshops)","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-08-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127936470","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 anytime code has been shown to help stabilize an unstable system over noisy channels. Among practical anytime codes, spatially coupled repeat-accumulate (SC-RA) anytime codes have been proven to provide outstanding asymptotic performance while offering a simple encoding process. However, in the finite block-length regime, high erasure/error floors are observed for the SC-RA anytime codes even as the decoding window size (decoding delay) is enlarged. In this paper, to alleviate the high erasure/error floors problem, novel syndrome-based hybrid automatic repeat request (HARQ) schemes are designed for the SC-RA anytime codes over the binary erasure channel (BEC) and the binary input additive white Gaussian noise (BI-AWGN) channel, respectively. Simulation results show that the proposed syndrome-based HARQ schemes offer better decoding performance and spectral efficiency than the prior-art anytime code HARQ schemes.","PeriodicalId":201450,"journal":{"name":"2023 IEEE/CIC International Conference on Communications in China (ICCC Workshops)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-08-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130689505","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}

This paper proposes a sensing method for passing-object detection, in which the channel state information (CSI) is combined with long short-term memory fully convolutional network (LSTM-FCN). In the method, the CSI is firstly extracted from the multiple antennas and multiple subcarriers, and the transmission waveform is based on the frame structure of the IEEE 802.11ac protocol. Then, the principal components analysis (PCA) is applied to reduce the dimension of CSI data. At the model train stage, the LSTM-FCN is applied to train the first principal component information of CSI data.

In this paper, two new types of DDS-based QC-LDPC codes are proposed, which contain all-zero circulants and possess girth at least eight and girth at least ten, respectively. Numerical simulations show that the new codes have good performance in AWGN channels.

To improve the performance, channel log-likelihood ratios are used to prevent miscorrections, which increases negligible computational complexity and decoder data flow. By properly selecting components, we can construct low-floor BCH-SPC product and staircase codes with a smaller blocklength (or decoding-window size) and a faster speed of convergence compared with the conventional product-like codes with both BCH components.

The time difference of arrival (TDOA) is a typical method for 5G NR positioning. In response to the low solving accuracy and slow convergence in traditional iterative or non-iterative TDOA algorithms, a 5G PRS signal positioning method based on the improved sparrow search algorithm (ISSA) is proposed in this paper. In combination with the characteristics of the 5G PRS signal, a model for downlink TDOA location is established. The initial positioning result is introduced into the ISSA algorithm to reduce the search times and optimize the fitness function. Consequently, the positioning accuracy is improved. Moreover, the ISSA algorithm is used to verify the positioning performance of the 5G PRS signal under different parameter configurations.

In our previous work, considering the practical rectangular pulse shaping and fractional Doppler shifts, a novel pilot pattern for Zero-Padded OTFS channel estimation was proposed, which can significantly reduce the pilot power of the embedded pilot scheme based on compressed sensing. To further improve the accuracy of the channel estimation, this paper presents a simplified model-driven residual network (ResNet) to refine the initial results. The proposed ResNet has a smaller input size and thus, lower training complexity by leveraging the beneficial features of the delay-Doppler (DD) domain channel. Simulation results demonstrate that the proposed simplified ResNet outperforms the preliminary estimator in terms of normalized mean square error (NMSE) performance. And the former can obtain more than 5 dB and 4.5 dB gain over the latter in the embedded pilot case and our proposed pilot pattern, respectively.
