  • Interference cancellation equipment
    Patent number: 7463733
    Abstract: An interference cancellation method for use in a communications system in which a plurality of communication paths are arranged to transmit and receive respective analogue signals comprises effecting an initialization phase to calculate, for each path, the interference effects of the signals transmitted on that path on the signals received on each of the other paths, and storing for each a plurality of weighting factors representing the interference on each of the other paths respectively. During transmission, said weighting factors are used to generate from the transmitted signal on one of the said paths and to apply said cancellation signals to signals received on said other paths, thereby to cancel the interference effect of said transmitted signals.
