一种测度MIMO-OFDM系统总体资源效率的方法
在定义归一化带宽和归一化信噪比,并构建需求平面模型的基础上,提出了一种测度数字调制系统总体资源效率的方法,对多天线正交频分复用（MIMO-OFDM）系统进行了分析,得出MIMO-OFDM系统在不同的检测算法、不同调制方式下的总体资源效率.主要结论为：MIMO-OFDM系统在最大似然检测算法下是最优的,其总体资源效率相对较高;基于正交振幅调制的总体资源效率高于基于多进制相移键控调制的,同时它的整体资源效率伴随着M的增加而提高....

Based on the model, a method of measuring the o- verall resource efficiency of the MIMO-OFDM system is proposed. This method obtains the overall resource efficiency of the MIMO-OFDM system under different detection algorithms and different modula- tion. The main conclusion is that the MIMO-OFDM system with the maximum likelihood detection algorithm has the relatively high overall resource efficiency, and using M-ary quadrature amplitude modulation （MQAM） has higher overall resource efficiency than employin |
