Rate‐compatible spatially coupled LDPC code ensembles by partial repetition extension
IET Communications, Volume 17, Issue 2, Page 246-252, January 2023., 2023 Abstract Herein, one partial repetition extension method is proposed to construct the rate‐compatible spatially coupled low‐density parity‐check (RC‐SCLDPC) codes. For each position of the base SCLDPC code, a certain proportion of the variable nodes are first selected randomly and then repeated a certain number of times.

A Time Delay Prediction Model of 5G Users Based on the BiLSTM Neural Network Optimized by APSO‐SD
Journal of Electrical and Computer Engineering, Volume 2023, Issue 1, 2023., 2023 To address the problems of 5G network planning and optimization, a 5G user time delay prediction model based on the BiLSTM neural network optimized by APSO‐SD is proposed. First, a channel generative model based on the ray‐tracing model and the statistical channel model is constructed to obtain a large amount of time delay data, and a 5G user ray data ...

IET Communications, Volume 16, Issue 18, Page 2219-2239, November 2022., 2022 Abstract In non‐orthogonal multiple access (NOMA) systems, it may not be advisable to send the superimposed signal of all users to individual users with retransmission requirements during the retransmission phase. This paper investigates a novel cognitive radio network based on hybrid NOMA/orthogonal multiple access (CR‐H‐NOMA/OMA) in underlay spectrum
