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, each modelled by the Rician and Tikhonov distributions respectively. As an example, the jitter performance of turbo coded signals are evaluated over 1+D / PRSC channel with different fading parameter K, effective signalto-noise ratio in the carrier tracking loop a, iteration number and data block size N. The numerical results clearly demonstrate the error performance degradation due to both amplitude fading and phase noise process.
