Performance of Stack Equalizer Over Frequency Selective Fading Channels

Abstract

In this paper the performance of the low complexity modified stack equalizer over frequency-selective fading channels is inspected. With the help of simulation results it is illustrated that by sacrificing the computational complexity insignificantly the performance of the modified equalizer can be made closer to optimum. This equalizer can be used at the receiver of uncoded systems or bit interleaved coded systems with iterative receivers.
