Abstract :
A new scheme of detection for multiple access channel is investigated, which consists in the combining of PIC-like detection and joint decoding of LDPC codes. The joint decoding is first studied through the use of LDPC codes over Galois extensions of binary field for the AWGN multiple access channel. Then, a hierarchical MC-CDMA system which uses both parallel interference canceler and joint detection is implemented and simulations show that it can provide a substantial improvement without any complexity growth of the emitter in a MC-CDMA like up-link framework
