AB - The chaotic signal is a relatively new field in communication systems. Motivation derives from the advantages offered by chaotic signals, such as spread spectrum, robustness in multipath environments and resistance to jamming. Chaotic signals are non-periodic, broadband, and difficult to predict and to reconstruct; they may be generated by mathematical map functions, electronic circuits or laser optics. Their properties coincide with requirements for signals used in communication systems, in particular for secure communication systems. The study in this paper is focused on one of the methods, proposed to send binary messages by chaotic signals- the chaos shift keying (CSK) approach. Each symbol to be transmitted is coded as a discrete chaotic signal, which is generated by a chaotic map. The symbols are detected at the receiver by coherent detection technique. The purpose in this paper is to present the error probability of a coherent CSK digital system under the influence of additive white Gaussian noise (AWGN), assuming ideal synchronization at the receiver. The solution for the error probability has been derived, in terms of the signal-to-noise power ratio.
