Abstract
A technique includes performing non-joint demodulation of a desired signal in response to a carrier-to-interference ratio estimate for a received signal being greater than or equal to a threshold level, the non-joint demodulating being based on first channel impulse response coefficients associated with the desired signal and second channel impulse response coefficients associated with one or more interfering signals. The technique includes determining the second channel impulse response coefficients based on a first cross-correlation function between the received signal and a training sequence of an interfering signal of the one or more interfering signals, determining the first channel impulse response coefficients based on a second cross-correlation function between the received signal and a training sequence of the interfering signal, and determining a time difference between a time value of a peak in the first cross-correlation function and a time value of a peak in the second cross-correlation function.
