Parallel Combinatory Spread Spectrum (PC/SS) communication system has higher data transmission capability and bandwidth efficiency than conventional Spread Spectrum (SS) communication system.Meanwhile, PC/SS system must correctly select all maximal r PN sequences from M PN correlations, otherwise it will cause a lot of error data.The existing algorithm has no ability of detecting and correcting a random misjudging sequence.To solve this problem, PCSS communication system based on the method of successive contrast (SC/PC/SS) is proposed in this paper and performances are analyzed.The SC/PC/SS system can detect and correct a sequence error.Theoretical analysis and simulation results show that the BER performance of the SC/PC/SS system is lower than conventional PC/SS system in the same situation.Without additional hardware and slightly increase in complexity, it can improve the communication environment of 1 dB.
