Abstract
A communication system includes a transmitter segment at a source location inputting a plurality of input signals to be transmitted. The input signals are transformed to wavefront multiplexed signals (WFM signals), and the WFM signals are modulated into WFM waveforms. The WFM waveforms are transmitted through a segment of propagation to a receiver segment; wherein the segment of propagation includes a plurality of UAV based transmission channels among the WFM waveforms; wherein the WFM waveforms are transmitted over the transmission channels; wherein the receiver segment receives the WFM waveforms from the transmission channels. Demodulation is performed on the received WFM waveforms to convert the received WFM waveforms to received WFM signals individually. A wavefront de-multiplexing transform is performed on the received WFM signals to recover individual desired signals.
