Signal Shaping for Two-User Gaussian Multiple Access Channels with Computation: Beyond the Cut-Set Bound
Zhiyong Chen, Hui Liu
In this paper, we investigate the signal shaping in a two-user discrete time memoryless Gaussian multiple-access channel (MAC) with computation. It is shown that by optimizing inpu…

Iterative detection and decoding for SCMA systems with LDPC codes
Baicen Xiao, Kexin Xiao, Shutian Zhang +3
Sparse code multiple access (SCMA) is a promising multiplexing approach to achieve high system capacity. In this paper, we develop a novel iterative detection and decoding scheme f…
