In this paper, the performance of turbo coded signals are investigated over Wireless Local Loop (WLL) environment with no side information on the phase noise and and no channel state information (CSI). We assume that the transmitter and the receiver are point-to-point microwave links, separated by WLL which is modelled as 1 + D-n /Partial Response Microwave Channel (PMRC) with realizable and practical medium parameters. Here, the combined effects of the nonideal coherent receiver on the phase of the received amplitude and of a noisy carrier reference are considered, each modelled by the Rayleigh and Tikhonov distributions respectively. As an example, the jitter performance of turbo coded signals are evaluated over 1 + D /PRMC with effective signal-to-noise ratio in the carrier tracking loop, fading parameter, iteration number and frame data block size. The numerical results clearly demonstrate the error performance degradation due to both amplitude fading and phase noise process.
