Abstract

A new suboptimum interference cancelling receiver called IRC-DDFSE is proposed that combines IRC-MLSE and DDFSE. The proposed receiver consists of a T/2-spaced whitened matched filter and T/2-spaced IRC-DDFSE receiver which is implemented by using a Viterbi algorithm. Simulation results show that at the BER of 10^-3 IRC-DDFSE gives 8~21 dB gain compared to MC-DDFSE for highly dispersive channels, while its complexity increase is marginal
