提出了一种新的位置码并行组合扩频通信系统。PC/PC/SS系统在高斯信道下可以设计成具有比普通PC/SS系统高几倍的数据传输能力。在所提出的系统中，位置码的调制被应用到每个同时发送的PN序列。分析了系统的误符号率和平均误比特率性能，以评估系统的性能。此外，PC/PC/SS系统比PC/SS和M-ary/SS系统具有更好的保密性能。
A novel position code parallel combinatory spread spectrum (PC/PC/SS) communication system is proposed in this paper. PC/PC/SS system can be designed to have higher data transmission capability, even several times compared to ordinary PC/SS system on Gaussian channel. In the proposed system, modulation of position code is applied to each simultaneously transmitting PN sequences. The symbol error rate and average bit error rate performances are analyzed to evaluate the performance of the proposed systems. Furthermore, PC/PC/SS system has excellent secret property than PC/SS and M-ary/SS systems.
