IEEE802.11g系统均衡技术研究及算法仿真

Channel equalization technology and algorithm simulation based on IEEE802.11g

介绍了IEEE802.11g系统的信道特性及其均衡原理,重点对基于训练序列、基于导频结构的信道均衡算法进行深入分析,提出了一种适用于无线信道时变衰落特性的自适应算法,与TS算法、LS算法进行了对比分析,并给出了相应的性能仿真结果。

The channel speciality in IEEE802.11g and principle of channel equalization technology are described comprehensively in this paper, and the emphases are put on the analysis of the channel estimation methods which use training sequences and pilot tones, furthermore we put up a new channel equalization algorithm based on adaptive filter principle. At last, the performance simulation is given and analyzed among the algorithm of TS, LS and the adaptive filter.
