1. A method of communicating, which comprises:

  • generating a coded orthogonal frequency division multiplexed (COFDM) communications signal as a plurality of subcarriers; and

    turning ON and OFF selected subcarriers while also frequency hopping and spreading the selected ON subcarriers over the frequency domain based on a fixed or variable sample rate to reduce average power for enhanced Low Probability of Interception/Low Probability of Detection (LPI/LPD) and also allow for more transmit power within a spectral mask.
