摘要
在无线通信系统中,如何最大限度地削弱信道及通信设备中的不利因素对通信质量的影响具有重要意义。通过对CDMA通信系统模型的建立,基于H∞控制理论设计该CDMA系统中的回路滤波器,用于最大限度减小信道衰落,MAI等对SINR的影响。该回路滤波器是利用遗传算法(GA)求解的,并在之后的仿真中验证了其在提高通信系统SINR的重要作用。
In the system of wireless communication,it is significant to minimize the worse-case variance of the received SINR caused by channel fading,MAI,AWGN and so forth.Firstly,this paper depicts the model of CDMA.Then,a loop filter is designed by H∞ control theory.Genetic Algorithm (GA) is adopted to solve the proposed loop filter.To confirm the performance of the designed filter,a simulation result is given in the end.
