Evaluation of MIMO/SA system performance based on fuzzy analytic hierarchy process

The communication performance of multiple-input multiple-cutput smart antenna(MIMO/SA) communication system is investigated with a fuzzy analytic hierarchy process method.The factors that influence multi-antenna systems are analyzed,and the hierarchical structure model is established.Subsequently,the weights of each index are calculated.The membership of each index is obtained according to the principle of fuzzy mathematics.Finally,the fuzzy comprehensive evaluation of the combination system is derived.The validity and accuracy of the evaluation method is confirmed by the simulation.This method provides a good reference for the application of MIMO/SA technologies.
