Abstract

This paper describes the multiple access performance of parallel combinatory spread spectrum (PC/SS) communication systems in nonfading andRayleigh fading multipath channels. The PC/SS systems can provide thehigh-speed data transmission capability by transmitting multiple pseudo-noise sequences out of a pre-assigned sequence set. The performanceis evaluated in terms of average bit error rate (BER) by numerical computation. In nonfading white gaussian channel, the PC/SS systems are superior to conventional direct sequence spread spectrum (DS/SS) systems under the identical spreading factor condition. In Rayleigh fading channel, the performance of the PC/SS system without diversity is poorer than that of the DS/SS system. By including the explicit and implicit diversity, the performance of the PC/SS system becomes better than that of conventional DS/SS systems. A longer spreading sequence is assignable to a PC/SS system having the spreading factor equal to that inthe conventional DS/SS system. Hence, the error control coding is easily. It is found that the PC/SS systems including diversity and Reed-Solomon coding improves the multiple access performance.
