1. A method for processing and de-interleaving a received signal, comprising:

  • receiving a continuous wave radio frequency signal and front end processing the radio frequency signal to filter, amplify and down-convert the radio frequency signal to produce a down-converted ingoing signal;

    converting the ingoing signal from a time domain signal to a frequency domain signal wherein the frequency domain signal comprises a plurality of tones arranged in a first sequence;

    tone de-interleaving the plurality of tones by re-arranging the first sequence of tones into a second sequence;

    producing a specified number of tones from the second sequence to a corresponding specified number of detector arrays that are each operable to generate a bit stream portion therefrom; and

    combining the bit steam portions produced by the detector array to create an ingoing bit stream;

    bit de-interleaving the ingoing bit stream to create a de-interleaved bit stream that, without transmission interference, matches an outgoing bit stream in a transmitter prior to scrambling and interleaving by the transmitter that generated the received signal.
