ABSTRACT:
The present invention provides a post-channel estimate phase corrector for use with a multiple-input, multiple-output (MIMO) receiver employing M receive antennas, M being at least two. In one embodiment, the post-channel estimate phase corrector includes a pilot sequence coordinator configured to receive a pattern of pilot sequences from the M receive antennas during data symbol time periods. The post-channel estimate phase corrector also includes a phase calculator coupled to the pilot sequence coordinator and configured to calculate phase corrections for individual channel estimates based on the pattern of pilot sequences.
