Spatially-coupled irregular LDPC codes by non square superposition matrices are proposed. Starting with a binary base matrix and replacing non-zero entries in the base matrix by superposition matrices produces a parity-check matrix and its corresp...

This paper considers spatially coupled repeat accumulate (SC-RA) coded interleave-division multiple-access (IDMA) systems with segmented interleavers. Each user employs an SC-RA encoder and a spreader followed by user-specific segmented interleave...

A K-user nonbinary parallel concatenated code (PCC) is proposed for a Gaussian MAC with symbol synchronization, equal-power, and equal-rate users. In a K-user q-ary PCC over finite field GF(q), each user employs a parallel concatenated code, with ...
