Approximate ML Detection for MIMO Phase Noise Channels

Abstract : We consider the MIMO communication channel impaired by phase noises at the transmitter and receiver. We focus on maximum likelihood detection for uncoded single-carrier transmission. We derive an approximation of the likelihood function , and propose the so-called self-interference whitening (SIW) algorithm. While the exact ML solution is computationally intractable, we construct a simulation-based lower bound on the error probability of ML detection. Numerical experiments demonstrate that SIW is, in most cases of interest, very close to optimal with moderate phase noise. Surprisingly, such near-ML performance can be achieved by applying only twice the nearest neighbor detection algorithm.
