Abstract :
This paper presents the results of the investigation of a chaotic multi-user modulation method, called chaotic phase shift keying. Only one chaotic sequence generator exists in each transmitter and receiver. We present the theory behind their operations, as well as the bit error rate derivation. It was found to have better performances, confirmed by analytical and simulation results, than the chaotic shift keying (CSK) system, which requires two chaotic sequence generators in each transmitter and receiver.
