✦ Synopsis

In this letter, we in¨estigate a chaotic synchronization-based ( ) secure communication system at radio frequency RF . In the system, the information signal, which is encrypted in the baseband by the use of a chaotic system, is modulated and transmitted in the RF band. At the recei¨er, the encrypted signal is demodulated and then decrypted by the use of chaotic synchronization. Experiments conducted at both baseband and RF ¨erify our theoretical analysis, and pro¨e the feasibility of our proposed communication system.
