MULTICARRIER RECEIVER AND METHODS OF GENERATING SPATIAL CORRELATION ESTIMATES FOR SIGNALS RECEIVED WITH A PLURALITY OF ANTENNAS

摘要

In a multicarrier receiver, spatial correlation estimates are enhanced by multiplying by weighting values generated from a channel length estimate. The channel length estimate is calculated from a channel estimate (e.g., an estimate of the channel response function) and a signal-to-noise ratio estimate. The spatial correlation estimates represent the correlation between frequency-domain samples from different antennas.
