| Abstract: | 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. |
