【Abstract】 The application of a hybrid genetic algorithm for the multi-user detection of mobile communication is discussed. Through analyzing the system block-diagram and the performance of simulated annealing genetic algorithm, the feasibility of using this algorithm in the multi-user detector is studied theoretically, and simulated in computer, he results have shown that the detector suggested can effectively solve the multiple access interference and suppress the near-far-effect and it’s performance is close to the optimal multi-user detector and obviously superior to the conventional detector.更多还原
