Iterative non-coherent detected DPSK systems in fast fading channels

Research output: Chapter in Book/Report/Conference proceeding › Conference contribution

Abstract

In this contribution, we study the property of FEC-coded differential PSK schemes with iterative non-coherent detection suitable for high mobility applications. Two distinct iterative non-coherent reception algorithms are proposed, in which decision feedback differential detection (DFDD) is used either to generate symbol probabilities or to predict the channel estimates. Turbo processing is employed in both schemes to progressively bridge the performance gap between coherent and non-coherent receivers by iteratively exchanging extrinsic information. Simulation results suggest that our proposed DFDD assisted iterative non-coherent DPSK trellis detection scheme is capable of delivering performance very similar to previous schemes reported in the literature, while being much simpler.
