Abstract

A Quasi-synchronous CDMA system using a ZCZ code called a ZCZ-CDMA system can remove co-channel interferences, simplify hardware design, and achieve fast (less latency) transmission, due to enhancement in Frame synchronization techniques. Inter-symbol interference and co-channel interference appearing in frequency-selective Rayleigh fading channels influence the bit error rate performance. This paper proposes a ZCZ-CDMA system with block coding and channel estimation techniques to improve the performance.
