ICA_for_Multi_User_Detection_in_CDMA_system
- Blind Source Seperation (BSS) now is a important technology. Independent Component Analysis (ICA) is the main technique of BSS. Suppose we mix many non-Gausse signal sources,ICA can seperate the mixed signal to orignal signals without any information

CDMA-2USER
- 二用户CDMA系统，信道为加性高斯信道，使用BPSK调制，15位M序列扩频，可以正确解扩解调。 输出为2用户的基带信号、扩频信号、PSK调制信号、解调信号的时域和频域特性，给出两个用户分别的误码率。 -Second, the user CDMA system, channel for the additive Gaussian channel, using BPSK modulation, 15 M Sequence Spread Spectrum, you can correct demo
SHIYAN_3
- 利用M函数仿真扩频通信系统。6个用户的CDMA的同步通信系统，每个用户利用L＝31的Gold码，进行扩频，信道为AWGN信道，接收端利用匹配滤波器进行检测。绘出当N＝10000个发射比特下，SNR＝0：15（dB）时的误码率曲线。 -M function simulation using Spread Spectrum Communication System. 6 simultaneous users of CDMA communication system, each user of t
MCCDMA
- This mfile simulates Multicarrier CDMA with three equalization methods (Zero Forcing, MRC and EGC). Also this simulation is designed for two users.
WalshHadmard
- Walsh-Hadamard codes are mutually orthognal codes, thus when used in synchronous CDMA, the interference between users is zero. This programm generates Walsh-Hadamard codes and also checks the orthogonality. You can change the code length by
