Abstract

We propose a new turbo code noncoherent detection scheme based on a novel a-priori probability processor (APP). Using this method, many turbo encoders can be used without a change in the code or in the modulation, and without a significant change in the structure of the iterative decoder. Simulation results of this method are presented for various phase noise levels. We show a degradation of 0.7 dB from the coherent detection of the same codes
