摘要： A method for phase noise detection in a MIMO communication system, comprises the step of computing an initial estimate of phase using received pilot symbols (91). A phase follows (92) for interpolating between successive pilot symbol phase estimates to obtain a coarse resolution reference phase estimate. Then, it follows a phase (93) for computing a fine resolution estimate of phase using said coarse resolution phase estimate together with data expressing characteristics of known phase noise processes, applying an expectation maximization (EM) algorithm. The application of the EM algorithm can be further refined using improved symbol decisions from a FEC decoding.
