Abstract

We consider a low-cost code shift division multiple-access (CSDMA) scheme, in which user-specific shifting is used to replace user-specific interleaving in interleave division multiple access (IDMA). We also outline a low-cost Gaussian approximation (GA)-based linear minimum mean square error (LMMSE) message passing detection technique for CSDMA. We show that CSDMA can offer almost the same performance as the original IDMA in low-density parity-check (LDPC) or turbo coded systems, but with considerably lower implementation cost.
