Abstract :
A digital communications keying concept that applies stochastic processes rather than deterministic waveforms is introduced and demonstrated. The technique implies a higher degree of security that conventional digital communications systems, reducing the risk of eavesdropping. The resulting receivers are non-coherent, and simpler than those of spread spectrum and chaotic encoders.
