Abstract
Techniques to adaptively apply interference rejection combining (IRC) for signal demodulation, include estimating an impairment covariance matrix, computing an interference correlation metric based on the determinant of the estimated impairment covariance matrix, selecting an interference correlation threshold, comparing the interference correlation metric with the threshold to determine if IRC should be used for demodulation, estimating a desired signal covariance matrix, computing a desired signal correlation metric based on the determinant of the desired signal covariance matrix, selecting desired signal correlation threshold, comparing the desired signal correlation metric with the desired signal correlation threshold to select one of the supported detection algorithms, filtering the received signal and associated channel matrix, and passing the whitened signal and channel matrix to the selected detection algorithm to generate estimates of code bits, if IRC is enabled. If IRC is disabled, no whitening is applied to the received signal and channel matrix.
