Abstract:
1. A method of channel tracking, the method comprising: computing, with a transceiver device, an estimate of a multiple input, multiple output (MIMO) channel; computing, with a matrix equalizer computational device of the transceiver device when the matrix equalizer computational device is not needed for equalization, an equalizer to be applied to signals received via the MIMO channel, wherein the equalizer is initialized based on the estimate of the MIMO channel; applying, with the matrix equalizer computational device, the equalizer to a received signal; demodulating, with the transceiver device, the received signal to generate a demodulated signal; decoding, with the transceiver device, the demodulated signal according to an error correction code to generate decoded data; re-encoding, with the transceiver device, the decoded data according to the error correction code to generate re-encoded data; re-modulating, with the transceiver device, the re-encoded data to generate a re-modulated signal; comparing, with the transceiver device, the received signal to the re-modulated signal; updating, with the-transceiver device, the equalizer based on comparing the received signal to the re-modulated signal; and after updating the equalizer, applying, with the matrix equalizer computational device, the equalizer to the received signal.
