1. A method for reducing the effects of inbound interference in a powerline transmission system comprising the steps of:

  • receiving a first signal on a first line of said transmission system, said first signal comprising a modulated carrier signal component and an interference component;

    receiving a second signal on a second line of said transmission system, said second signal comprising a modulated carrier signal component and an interference component;

    adjusting at least one characteristic of at least one of said first and second signals to reduce the effects of external interference on said transmission system; and

    determining adjustment parameters by adjusting said at least one characteristic of at least one of said first and second signals until the output of a differential receiver operating on said first and second signals is zero.
