DSSS
说明: 设计一个有干扰的直接序列扩频通信系统, PN码由m序列产生器产生,经过高斯白噪声信道。在接收端接收到的信号包括“有用信号+高斯白噪声+干扰”,将接收信号进行解扩,判决,得到用户的信号检测结果,绘制不同的扩频增益(增益值为10,30,50)下,误比特率随信噪比Eb/N0的变化曲线。(Design of a direct sequence spread spectrum interference system, PN code generated by the m sequence generator, after white Gaussian noise channel. Receives the signal at the receiver, including " useful signal+ Gaussian white noise+ interference" , will receive the signal despreading, judgments, get the user' s signal test results, draw a different spreading gain (gain value of 10,30, 50), the BER curves with the signal to noise ratio Eb/N0.)
