1. A 1553 communication system comprising:

  • a data bus configured to carry primary signals having a 1 Mb/s 1553 component and a non-1Mb/s 1553 component;

    an input port configured to receive a signal from the data bus, via an analog front end block and a sampling unit configured to sample the received signal;

    a 1553 data extraction block connected to the input port, configured to extract 1553 data from the sampled signal and to output synthesized 1 Mb/s 1553 data; and

    a cancellation circuit comprising;

    an interference generation unit configured to produce an interference signal based on the synthesized 1 Mb/s 1553 data; and

    a cancellation unit configured to subtract the interference signal from the sampled signal and to produce an output signal.
