In this paper, we introduce a novel receiver for the detection of data in the presence of rapidly changing nuisance parameters and additive noise. This receiver uses a parallel structure, and its output approximates a Maximum Likelihood detection of the data. We apply this receiver to the special case of data detection of MPSK in the presence of rapidly changing unknown phase; here, the rate of phase change is such that phase change over two symbols is negligible, but it is not necessarily negligible over a longer interval. The unknown-phase receiver we propose outperforms DPSK by 1.5 dB. We also compare the performance of this receiver with that of Multiple Symbol Differential Detection (MSDD). Except under very slow phase change conditions, this receiver outper-forms MSDD. Furthermore, our unknown-phase receiver is easy to implement, requiring a relatively low complexity.
