针对群正交分组多载波码分多址（group-orthogonal multi-carrier CDMA,GO-MC-CDMA）系统中合理的分组能够获得良好的频率分集效果以及保证最大似然检测的可行性等特点,通过运用MATLAB/simulink得出了仿真模型,并且通过对GO-MC-CDMA系统内部分组的大小进行调整,对模型的分析和仿真测试得出不同的分组对系统性能影响较大。根据系统不同分组时的乘法复杂度大小以及误码率大小的综合分析,得到GO-MC-CDMA系统通信性能最优时的分组数。

According to the features that the reasonable group of GO-MC-CDMA （ group-orthogonal multi-carrier CDMA） system could achieve a good Frequency diversity effect and the feasibility of maximum likelihood detection, this paper gives the model of GO-MC-CDMA system by MATLAB/simulink, which can change the size of group. Through the simulation analysis it can be conclude that different size of group has a big influence on system performance. By analysis the results of simulation and computation complexity comprehensive the most appropriate number of size can he obtained. It＇ ...
