Performance of turbo coded signals over partial response fading channels with imperfect phase reference

Abstract

In this paper, the performance of turbo coded signals are investigated over a new channel model, denoted as 1 +/- D-n / Partial Response Fading Channels (PRFC) with imperfect phase reference. The combined effects of the 1 +/- D-n /PRFC and nonideal coherent receiver on the phase of the received amplitude and of a noisy carrier reference are considered. The numerical results demonstrate the error performance degradation due to both amplitude fading and phase noise process.
