摘要
基于TMS320VC5410微处理器开发平台,对直扩序列保密通信系统进行了研究。给出可编程m序列的C代码及其在数字信号仿真/实验系统DES320PP-U上的相关链接配置文件,实现周期在271、291、2101和2111内可编程变化的m伪随机序列;经调试与仿真,结果表明m伪随机序列信号的周期、初相位可编程随机变化是满意的,采用该方法可以实现可编程m序列随机发生器的设计。
Based on TMS320VC5410 microprocessor developing platform, the direct spread spectrum （DSS） sequence secrecy communication system is studied. C code of programmable m sequence and its linker eommand file with regard to digital signal （DS） simulation and experimentation system 320PP-U are given. The programmable variation m sequence with the cycle of 2^7-1,2^9-1,2^10- 1 and 2^11- 1 are realized. These results indicate that the cycle ofm pseudo-random sequence and programmable random variation of primary phase are satisfied by debugging and simulating. The design of the programmable m sequence generator is realized with the proposed method.
