Abstract:
1. A multicarrier receiver that communicates over a plurality of subcarriers and spatial channels, comprising: an equalizer to multiply frequency domain signals generated from each of a plurality of receive signal paths by an equalizer coefficient matrix to remove at least some crosstalk and noise to generate spatially equalized frequency domain signals for each subcarrier; a soft-bit demapper for each spatial channel to multiply the spatially equalized frequency domain signals by soft-bit weights for use in generating soft bits; and a training unit to generate the equalizer coefficient matrix from a noise correlation matrix, a channel estimate matrix and an average energy of transmitted sub-symbols for each subcarrier and to generate the soft-bit weights from effective channel taps, wherein the effective channel taps comprise only diagonal elements of an effective channel matrix, and wherein the training unit generates the diagonal elements of the effective channel matrix from the equalizer coefficient matrix and the channel estimate matrix.
