A CDMA multiuser detector with block channel coding and its performance analysis under multiple access interference

This paper introduces an error controlled Decision feedback (ECDF) multiuser receiver, which integrates a successive canceller with linear block channel coding to mitigate Decision error propagation. In particular, it uses a switching successive cancellation feedback loop, which can be open if excessive bit errors occur to prevent Decision error propagation. The results of computer simulation show that the ECDF receiver possesses advantages in terms of near-far resistance and BER over many reported schemes.
