BER Performance Of Complex Parallel Combinatory Spread Spectrum Communication System
Lili Guo, Beiming Li · 2007
This paper presents a novel composite parallel combinatory spread spectrum (CPC/SS) communication system. CPC/SS system can be designed to have more higher data transmission capability than spread spectrum (SS) communication system, even several times on Gaussian channels compared to ordinary parallel combinatory spread spectrum (PC/SS) system. In the proposed system, modulation of position code and state are applied to each simultaneously transmitting PN sequences. The symbol error rate and average bit error rate are analyzed to evaluate the performance of the proposed systems. Furthermore, CPC/SS system has excellent secret property than PC/SS and CDMA communication systems.
