Abstract :
Quasi-synchronous CDMA systems, which can remove co-channel interference by means of synchronization control and use of a ZCZ code, are useful for Short-Range Wireless communications. This paper proposes a BFSK-ZCZ-CDMA modulation system which appears more advantageous in bit-error-rate performance over multi-path fading channels than ASK or PSK modulation scheme. In this system, a balanced ZCZ code and a quasi-coherent detection with IQ separation are used. The bit-error-rate performances over AWGN and fading channels are simulated.
