Abstract:
1. A method comprising: jointly demodulating a desired signal and one or more interfering signals of a received signal in response to a carrier-to-interference ratio estimate for the received signal being below a threshold level, the jointly demodulating being based on first channel impulse response coefficients associated with the desired signal and second channel impulse response coefficients associated with the one or more interfering signals; 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, wherein determining the second channel impulse response coefficients is further based on the time difference.
