Abstract
The present disclosure includes wireless communication systems with code-division multiple access with interference avoidance (CDMA-IA). In one embodiment, the wireless communication system includes a plurality of transmitters and a plurality of receivers. At least one transmitter of the plurality of transmitters is configured to detect unoccupied segments of spectrum occupancy of interference at one of the plurality of receivers, and spread power of a transmitted signal non-uniformly across a channel bandwidth that is much wider than an information bandwidth of the transmitted signal using a plurality of non-contiguous spectral segments that correspond to the unoccupied segments of the spectrum occupancy of the interference at the one of the plurality of receivers. At least one receiver of the plurality of receivers is configured to perform a demodulation process by coherently integrating the power of the transmitted signal over the plurality of non-contiguous spectral segments.
