摘要
通过仿真研究得出m序列、Gold序列的自相关函数特性和互相关函数特性。在理论分析的基础上,利用MATLAB软件编写程序对m序列、Gold序列的相关性进行了仿真研究。通过对仿真程序的调试与运行,得到了m序列、Gold序列相关函数特性曲线,实现了高精度仿真。仿真结果表明,m序列、Gold序列都具有尖锐的自相关特性和较好的互相关特性,在CDMA系统中可以广泛应用。
Through simulation studies, the autocorrelation functions and features of m sequence, Gold sequence are obtained. Based on theoretical analysis, the correlation of m sequence and Gold sequence is simulatedly studied by using software programming on MATLAB. Through commissioning and operating of the simulation program, the characteristic curve for correlation function of m sequence and Gold sequence is acquired, thus achieving a high-precision Gold sequences are associated with sharp simulation. Simulation results indicate that m sequence and Gold sequence are of sharp autocorrelation and better inter-correlation, and could be applied widely in CDMA system.
