ABSTRACT:
A sum of interference replica signals of other user that have been generated and synthesized is transmitted to each user at each stage. An interference replica signal of a present user generated at a stage previous to a present stage is subtracted from the synthesized replica signal. The remained interference replica signal is subtracted from the received signal, thus cancelling the interference generated by other user.
