Experiments on Direct Chaotic Communications in Microwave Band

We discuss a concept of Direct Chaotic Communications (DCC) that is based on the following ideas: (1) chaotic oscillator generates signals directly in a specified microwave band; (2) information component is put in the chaotic signal by means of formation of an appropriate stream of chaotic radio pulses; (3) envelope detection is used. The principle of communications is confirmed experimentally in microwave band. Transmission rates up to 100 Mbps are demonstrated.
