Channel tracking in a wireless multiple-input multiple-output (MIMO) communication system

摘要

An equalizer to be applied to signals received via at least one multiple input, multiple output (MIMO) channel is computed using a matrix equalizer computational device. The computed equalizer is applied to a received signal to recover an equalized representation of encoded data sent in a transmission. Errors are removed from the equalized representation of the encoded data to generate an error-corrected estimation of the encoded data sent in the transmission, and the equalized representation of the encoded data is compared to the error-corrected estimation of the encoded data. An updated equalizer is then computed to be applied to a subsequent signal based on the comparison.
