Abstract :
Code-phase-shift keying (CPSK) is a novel direct-sequence spread-spectrum (DS-SS) signaling system employing M different code phase shifts of a single pseudonoise (PN) code sequence for M-ary signaling. CPSK offers increasing thermal noise immunity as M increases, and totally mitigates the effect of carrier frequency tone interference. It maintains good performance in a Rician fading channel, and a RAKE receiver could be used to improve the performance in a Rayleigh fading channel. The improved power and bandwidth efficiency of CPSK makes it suitable for wireless local area network applications
