Abstract :
Chaos shift keying (CSK) is a modulation method in digital communication systems which makes use of chaos synchronization to send binary signals. This paper extends the existent method of chaotic phase-shift keying (CPSK), a form of CSK which utilizes in-phase and antiphase synchronizations. As the method is based on M-synchronization, it will be called M-CPSK. We give an example of a quaternary wireless communication system and examine the effect of noise in transmission channels on the system by computer simulation
