Performance Analysis of WiMAX System Base on AMC Optimized Algorithm
Aimed at WiMAX-OFDM system,an optimized algorithm for AMC was proposed from the angle of channel estimation.Simulation experiments were carried on in SUI channels which were typically slow fading,and influences of the traditional AMC technology and optimized AMC algorithm on performance of system were analyzed.Results show that the optimized AMC algorithm not only improves accuracy of channel estimation,but also reduces errors between the predicted signal-to-noise ratio and the actual SNR,which makes selected modulation and coding scheme more reasonable.Finally,the WiMAX system can obtain performance optimization.
