1. An interference canceller for use in a receiver that separates received communication signals (r) from a plurality of transmitters over a CDMA interface into a plurality of desired signals (d(k)), the interference canceller comprising:

  • a channel estimation processor for receiving the communication signals (r) producing individual impulse response estimates (A) for the plurality of desired signals (d(k)), said impulse response estimates coupled to a data estimation and interference canceller; and

    said data estimation and interference canceller receiving the communication signals (r) and said impulse response estimates (A) and outputting the plurality of desired signals (d(k)).
