Abstract: In this paper, we explore the issue that how many messages can be transmitted through one scalar chaotic time series. A scheme is proposed for modulating multiple messages into the system. Based on the adaptive parameter estimation method, provided that some special conditions are satisfied, such as the long-time persistent excitation condition or the long-time linearly independent condition, the carried information could be recovered at the receiver. This scheme has potential application in chaotic optical communication (COC). Its feasibility and effectiveness are demonstrated by numerical examples.
