1. A method for recovering data from a received signal comprising a first user pilot and an interference signal, the method comprising:

  • estimating the pilot from the received signal to generate a first-pass pilot estimate;

    cancelling the first-pass pilot estimate from the received signal to generate a first cancelled signal;

    estimating the interference signal from the first cancelled signal to generate an interference estimate;

    cancelling the interference estimate from the first cancelled signal to generate an interference-cancelled signal;

    re-estimating the pilot from the interference-cancelled signal to generate a second pilot estimate; and

    demodulating a signal derived from the received signal using the second pilot estimate to recover data from the received signal.
