We discuss the concept of Direct Chaotic Communication (DCC). The scheme is based on the following ideas: (1) the chaotic source generates chaotic oscillations directly in the specified microwave band; (2) information component is input by means of formation of the appropriate stream of chaotic radio pulses; (3) envelope detection is used. The principle of communication scheme is confirmed experimentally in microwave band. The transmission rates of 3.34, 10.0 and up to 70.0 Mbps are demonstrated. his only looks like the abstract.
