This paper presents a new communication scheme, named quadrature differential chaotic phase shift keying (QDCPSK), which is developed from M-ary phase shift keying, chaotic phase and quadrature chaos shift keying (QCSK). It has not only the advances and characteristics of chaotic communication systems, but also higher efficiency of band usage and transmitting speed. The performance of QDCPSK is simulated in context of AWGN channel and compared with the two methods, differential chaotic phase shift keying and quadrature chaos shift keying.
