摘　　要：研究了模拟退火遗传算法在移动通信系统多用户检测中的应用,通过分析系统框图、遗传算法和模拟退火算法的性能,对将其利用于多用户检测器中的可行性进行了理论阐述并进行了仿真,结果表明本文提出的多用户检测器可以有效的解决多址干扰和抑制远近效应,其性能接近最优多用户检测器,优于传统检测器。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.
