Abstract

A spread spectrum communication system includes a transceiver configured to transmit a spread spectrum waveform. The spread spectrum waveform comprises transmitted signals at varying frequencies within a radio frequency spectrum of operation. The frequency variation is controlled according to a hopping sequence. A spectral sensor of the communication system is configured to dynamically scan the radio frequency spectrum of operation and to generate channel occupancy data based upon the scans. A real time hopping sequence generator is configured to dynamically generate the hopping sequence in real time as a function of the channel occupancy data.
