Abstract

Different receiver structures that enable digitally modulated signals to be received in the presence of a number of similarly modulated cochannel interfering signals, which may additionally be dispersed in time owing to the influence of the channel, were investigated. Simplified MLSE techniques using decision feedback are analyzed mathematically and simulated. The performance of the different receivers in terms of complexity, channel estimation requirements and BER performance variation, are compared. These performances are obtained in the presence of AWGN and Rayleigh fading conditions
