LDPC Coded Multiuser Shaping for the Gaussian Multiple Access Channel
Alexios Balatsoukas-Stimming, Stefano Rini, Joerg Kliewer
The joint design of input constellation and low-density parity-check (LDPC) codes to approach the symmetric capacity of the two-user Gaussian multiple access channel is studied. Mo…
