摘要

研究了瑞利衰落信道下并行组合扩频(PC/SS)通信系统的多址性能。PC/SS系统通过从预先分配的序列集中发送多个伪噪声序列，具有高速数据传输能力。通过数值计算，以平均误码率来评价其性能。重点放在频率非选择性、缓慢衰落的信道上。研究发现，包括分集在内的PC/SS系统的多址性能优于传统的直接序列扩频系统。将Reed-Solomon编码应用于PC/SS系统，提高了系统的多址性能。

Performance evaluation of parallel combinatory SSMA systems in Rayleigh fading channel

The multiple access performance of parallel combinatory spread spectrum (PC/SS) communication systems in Rayleigh fading channel is studied. The PC/SS system has the high-speed data transmission capability by transmitting multiple pseudo-noise sequences out of the pre-assigned sequence set. The performance is evaluated in terms of average bit error rate by numerical computation. Focus is put on the frequency-nonselective, slowly fading channel. It is found that the multiple access performance of the PC/SS system including diversity is superior to that of conventional direct-sequence spread spectrum systems. Applying Reed-Solomon coding to the PC/SS system improves of the multiple access performance.<>
