We study code design for two-user Gaussian multiple access channels (GMACs) under fixed channel gains and under quasi-static fading. We employ low-density parity-check (LDPC) codes with BPSK modulation and utilize an iterative joint decoder. Adopting a belief propagation (BP) algorithm, we deriv...

We address the problem of LDPC code design forrelay channel in time-division mode based on a distributedstrategy: In the first time slot, the source transmits part of thecodeword. The relay and the destination receive it but only therelay can decode it. In the second time slot, the relay...

The design of LDPC codes is based on two successive decompositions of rectangular blocks of the parity check matrix into underlying rectangular blocks defining three different sizes of blocks q then v and w. The codeword length is variable through divisions by a factor of 2 of the size v ...
