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 generato

In this project we analyze and design the minimum mean-square error (MMSE) multiuser receiver for uniformly quantized synchronous code division multiple access (CDMA) signals in additive white Gaussian noise (AWGN) channels.This project is mainly bas

本文在传统分布式功率控制算法的基础上，考虑到代价函数的非负性，且存在一个正的最小值的特性，采用用户发射功率和信干比来定义用户的代价函数，引用了一种基于代价函数的功率控制算法。最后，本文利用MATLAB工具对该算法进行了仿真分析，验证了算法的有效性-Based on the traditional distributed power control algorithm based on, taking into account the non-negative Daijia function, a

. The reference simulator can be used to measure and plot the network capacity performance and signal to interference ratio (SIR) performance of LTE networks with the integer frequency reuse scheme with reuse factor 1 (IFR-1). Frequency reuse scheme
