摘要: Considers synchronous code-division multiple-access communications incorporating an outer error-control code for improved performance. The authors describe a reduced-complexity detector to be used as the inner decoder, and develop simple method computing reliability values bits produced by this decoder. is then decoded using algorithm that incorporates information. Simulations have demonstrated effectiveness of algorithm. >
