摘要
论文提出采用相关性较好的PN序列作为帧检测算法的前导码,通过比较m序列、Gold序列和M序列等几种常见PN序列的相关特性,发现m序列相关特性很好,但长度非常短,Gold序列较m序列长很多,实现较M序列简单,但其相关特性不很理想。文章通过仿真帧检测算法,验证了PN码作前导码的可行性和有效性,并为不同要求下的前导码选择提供了一定的依据。
This paper has used PN sequence to work as lead polit-code in the Frame Detection Algorithm .The simulation results shows that m sequence is the shortest but the relevant characteristics is best, the Gold sequences is longer with achieving more simple compared to M sequences, but its relevant characteristic is not very good. The Frame Detection Algorithm has verified the feasibility and validity of PN sequence as the lead polit-code, and provided certain basis to different cases.
