Abstract
A Radio Frequency (RF) receiver includes a RF front end and a baseband processing module coupled to the RF front end that is operable to determine equalizer coefficients for a composite signal that includes a first information signal and a second information signal. First and second information signal channel estimates and channel powers based upon training symbols are determined. A composite signal power is determined. A noise variance of the composite signal is determined based upon the first information signal channel power, the second information signal channel power, and the composite signal power. A plurality of equalizer coefficients are determined based upon the first information signal channel estimate, the second information signal channel estimate, and the noise variance of the composite signal.
