该程序源代码实现了CDMA通信系统性能的仿真，用MATLAB实现了直序、跳时、跳频以及M序列，GOLD序列等的产生，及在AWGN和RAYLEIGH环境下误码率的计算(The program source code to achieve the performance of CDMA communication system simulation, using MATLAB realize the direct sequence, time hopping, frequency hopping and M sequences, GOLD sequence generation, and in the AWGN environment and RAYLEIGH BER calculation)

说明：  Floyd算法,求两点间最小路径,很有用(Floyd algorithm for the minimum path between two points, very useful)

Direct sequence spread spectrum (DSSS) communication systems has been widely used in these years for its advantage of wide spectrum, low working Signal-to-Noise ratio (SNR), anti-interference, anti-multipath effect and capability of LPI and LPD. They are increasingly replacing conventional communication forms and obtaining extensively applications in modern military and commercial communication systems, for example, CDMA communication system, GPS , measuring and control system, satellite chain, identification of friend or foe and etc. Therefore, corresponding DSSS electronic counter technique becomes a big problem to solve in electronic warfare domain. DSSS electronic counter technique including blind detection, blind parameter estimation and spreading sequences estimation. For the issue of DSSS electronic counter technique of DSSS/QPSK signal damaged by strong additive white Gaussian noise (AWGN), the main research content in this dissertation as follow.
