1. A transceiver having self-interference suppression, comprising, within one transceiver device:

  • two or more transmitters comprising one or more signal generators for transmitting transmit signals having transmit center frequencies in a selected first subchannel; and

    one or more receivers having receiver inputs for simultaneously receiving a desired receive signal in a second subchannel and an undesired accumulated interference signal due to said transmitted signals; and

    at least one of said transmitters also comprising a precompensation circuit that modifies the transmit signals such that said accumulated interference signal at the receiver(s) inputs is reduced.
