Q_DSSS
- 直扩码分多址DS-CDMA是利用高速的WALSH正交码序列作为地址码,与多用户信息数据相乘得到信息数据的直接扩频信号,再经过BPSK调制后发送出去,经过AWGN无线信道的传输后,在接收端与本地产生的地址码进行相关检测,从中将地址码与本地码一致的用户数据选出,把不一致的用户数据删除。-DS-CDMA DS-CDMA is the use of high-speed WALSH orthogonal code sequences as address code, with multi-user in

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
Asynchronous_CDMA
- This the simulink file that demonstrates the fundametal principle of operation behind asynchronous CDMA systems using Welsh codes. The system performance can be evaluated by changing the processing gain at the transmitter and by increasing or decreas
