Abstract

In this paper, a receiver is proposed to combat intersymbol interference (ISI) generated over a frequency selective channel. The receiver is based on a symbol detector and a channel decoder separated by a deinterleaver. Through an iterative detecting-decoding process, using turbo-codes principle, the so-called turbo-detector manages to overcome frequency selectivity, especially over a Gaussian channel. Simulation results show the turbo-detector efficiency over both Gaussian and GSM channels
