1. A communication signal receiver comprising:

  • an input for receiving a communication signal, the communication signal comprising signal components; and

    a processor adapted to;

    receive the communication signal from the input, to estimate interference in the communication signal, wherein a first interference estimate is based on a first modulated symbol of a first signal component in the communication signal and a second interference estimate is based on a second modulated symbol of a second signal component in the communication signal;

    apply a first weight based on the first interference estimate to a first signal component of the communication signal; and

    apply a second weight based on the second interference estimate to a second signal component of the communication signal.
