Abstract:
1. A method of channel tracking within a communication system having a first transceiver device having a plurality of transmission antennas and a second transceiver device having a plurality of receiving antennas, the method comprising: computing an equalizer to be applied to signals received via at least one multiple input, multiple output (MIMO) channel using a matrix equalizer computational device when the matrix equalizer computational device is not needed for matrix equalization, wherein the equalizer is initialized to the inverse of a channel estimation matrix; applying the equalizer to a received signal to recover an equalized representation of encoded data sent in a transmission from the first transceiver device to the second transceiver device; removing errors from the equalized representation of the encoded data to generate an error-corrected estimation of the encoded data sent in the transmission; comparing the equalized representation of the encoded data to the error-corrected estimation of the encoded data; and computing an updated equalizer to be applied to a subsequent signal.
