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

This is aimed at exploring how rate control and adaptation of carrier sense threshold can affect spatial reuse (and hence aggregate throughput) in a multi-hop network.
Signal-to-Interference Noise Ratio (SINR) required for successful reception at t

When a UE moves away the serving eNodeB
(eNB) and becomes closer to the neighbouring eNB (see
fig.1), the strength of desired received signal decreases and
the ICI increases.The impact of ICI in LTE downlink can be
analysed according to the r

The model is built upon the assumption that the probabil-
ity distribution of available destinations among the bu ered frames at
the Base Station (BS) is approximately the same as the probability
distribution of the trac arriving to the BS, th
