Based on parameter modulation theory, a parameter observer is designed for the first order time-delay Logistic chaotic system. The unknown parameter of this system can be identified by transmitting a single signal,then the useful signal modulated in the parameter will be recovered successfully. By choosing different frequency signals as "0" and "1" a practical digital secure communications scheme is designed. Numerical simulation shows the effectiveness of the method.
