1. Multi - uesr detection ( mud ) refers to signal detection in multiple access communications . this detection has many good properties , such as decreasing multiple access interference , canceling out or moderating near - far resistance , able to decrease the requirement for output control , compensating the effects due to inoptimal orthogonality , improving system performance and increasing system capacity . mud is one of the methods that can overcome the mai in cdma with most potential and complete and becomes one of the critical techniques in the third generation mobile communication
   多用户检测是指多址通信中的信号检测,具有抑止多址干扰;消除或减轻远近效应;可适当降低对功率控制的要求;弥补扩频码互相关性不理想造成的影响;改善系统性能,提高系统容量等众多优点,是克服cdma多址干扰最有潜力、最彻底的一种方法,并已成为第三代移动通信标准中倡导的关键技术之一。
2. This paper firstly overviews the traditional pso algorithm , and introduces the stretching technique to avoid " premature " in pso and to improve the algorithm ' s ablity to search for a global optimum . the stretching technique is applied to the optimization process in mud . by viewing the objective function of mud as the algorithm ’ s fitness function , the multi - uesr detector based on the stretching pso ( spso ) is proposed
   本文首先在传统粒子群优化算法基础上,为避免基本粒子群优化算法“早熟”现象,提高算法全局寻优能力,引入了拉伸技术,并把其应用到多用户检测寻优过程中,将算法适应值设为最佳多用户检测目标函数,提出了基于拉伸技术粒子群优化算法的多用户检测器。
