Abstract:
1. A method comprising: jointly demodulating a desired signal and one or more interfering signals of a received signal using a Viterbi equalizer having an adaptive total number of states based on first channel impulse response (CIR) coefficients associated with the desired signal and second CIR coefficients associated with the one more interfering signals; determining the second CIR 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 CIR coefficients based on a second cross-correlation function between the received signal and a training sequence of the interfering signal; 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; and wherein determining the second CIR coefficients is further based on the time difference.
