Joint demodulation of a desired signal and an interfering signal based on a carrier-to-interference ratio estimate

An apparatus comprising:

• a channel estimator configured to estimate a carrier-to-interference ratio estimate for a received signal;
• and
• a demodulator configured to selectively perform joint demodulation of a desired signal and an interfering signal of the received signal based on the carrier-to-interference ratio estimate and a threshold level,
• wherein the demodulator is configured to perform the joint demodulation 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,
• wherein the channel estimator is further configured to determine the first channel impulse response coefficients associated with the desired signal and further configured to determine the second channel impulse response coefficients associated with the interfering signal,
• wherein the second channel impulse response coefficients are based on a time difference between a time value of a peak in a first cross-correlation function and a time value of a peak in a second cross-correlation function.

A non-transitory computer-readable storage medium comprising a set of instructions to direct a processor to perform acts of:

• jointly demodulating a desired signal and an interfering signal of a received signal in response to a carrier-to-interference ratio estimate for the received signal and 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 interfering signal;
• determining the first channel impulse response coefficients based on a first cross-correlation function between the received signal and a training sequence of the desired signal;
• determining the second 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.
