摘要
研究了信道质量和子载波调制方式、联合最优编码率和最佳调制方式与信道容量、频谱利用率的关系,提出一个使系统得到较高的频谱效率和信道容量的自适应编码调制算法。其中,系统的有效数据传输效率是根据信号干扰噪声比进行评估的。论证了MIMO-OFDM系统自适应编码调制算法,分析它的信道容量以及频谱效率,并进行仿真实验,给出算法的性能结果。
We have studied the quality of the channel and the sub-carrier modulation, and joint optimal encoding rate and the best modulation and channel capacity, spectrum utilization relationship proposed a high spectral efficiency and channel capacity of adaptive modulation and coding algorithms. Where in the effective data transmission efficiency of the system is based on the signal interference noise ratio assessment. In the paper, the performance results demonstrate adaptive modulation and coding algorithm for our MIMO-OFDM systems, analysis of its channel capacity and spectral efficiency, and simulation experiments given algorithm.
