摘要 Gold码是一种伪随机序列,由于其可供使用的伪随机序列数量较多,多用于多址通信中.本文介绍了Gold码的构造方法,并利用Matlab中的Simulink仿真系统进行仿真分析,仿真结果证明了该方法的正确性和可行性.并对Gold码序列的自相关函数值和同族内的互相关函数值进行了仿真计算. Gold sequence is a pseudo--random sequence, and it has greater number of sequence which can be used in multiple--access communication system. This paper introduces Gold sequence construction method, and it has been produced and simulated by Simulink of Matlab. The simulation results show the correctness and feasibility of this method. Auto--correlation function and cross--correlation function in the same Gold family have been simulated.
