Detection of turbo coded signals transmitted through ISI channels using the predictive iterative decoder

Abstract

This paper addresses the problem of detecting turbo-coded signals transmitted through channels that introduce inter-symbol interference (ISI). The receiver is simple to implement and it consists of a linear minimum mean squared error (MMSE) equalizer followed by a predictive iterative decoder (PID). Simulation results show that depending on the noise correlation, significant performance improvement can be obtained by using the PID, over that of the conventional iterative decoder (CTD).
