SC‐LDPC code design for Gaussian multiple access channel
Abstract
This paper presents the design and analysis of spatially coupled low‐density parity‐check (SC‐LDPC) codes for Gaussian multiple access channel (GMAC). For two‐user GMAC, we consider that each user encodes their messages by SC‐LDPC codes while joint belief propagation decoding is considered at the receiver. We present low complexity density evolution analysis of SC‐LDPC GMAC codes and show simple optimisation procedure. For the asymptotic case, we observe that SC‐LDPC code‐based GMAC code outperforms existing irregular LDPC code‐based GMAC code.

LDPC codes over Gaussian multiple access wiretap channel
The authors study the problem of two‐user Gaussian multiple access channel (GMAC) in the presence of an external eavesdropper, where all transmitted messages should be kept confidential against the eavesdropper. For this purpose, they propose a secure ...
