ABSTRACT:
Systems and techniques relating to processing information received from a spatially diverse transmission. In some implementations, a method comprises: obtaining a received signal that was transmitted over a wireless channel using spatially diverse transmission, the received signal comprising multiple subcarriers; and recursively computing a signal-to-noise-ratio (SNR) of the received signal while receiving channel response information of the wireless channel derived from the received signal; wherein the recursively computing comprises recursively updating a diagonal kernel matrix, the method further comprising generating an equalization matrix from the recursively updated diagonal kernel matrix, the equalization matrix being useable in equalizing the received signal across the multiple subcarriers.
