基于Matlab的CDMA通信系统仿真 - 1 - 通信系统综合设计与实践 1绪论 1.1课题背景及目的 20世纪60年代以来,随着民用通信事业的发展,频带拥挤问题日益突出。CDMA(Code Diveision Multiple Access,码分多址)通信,在使用相同频率资源的情况下,理论上CDMA移动网比模拟网容量大20倍,实际使用中比模拟网大10倍,比GSM要大4...
https://uk.mathworks.com/matlabcentral/fileexchange/?s_tid=gn_mlc_fx is the place to look for ready made pieces of code. People are not going to write complex code for you in Matlab Answers, especially when you give no details of what you even want. If there is nothing relevant on ...
