移动环境中IEEE 802.16d系统的信道估计研究
Research channel estimation for IEEE 802.16d in mobile environment
摘要
Abstract
This paper analyzed the channel estimation algortihms in the IEEE802.16d mobile system.In order to enhance the mobility of the system , porposed an linear model to approximate the time-varying characteristic of channel impulse response in the frequency domain during each frame.The simulation results show that the proposed methods can still provide accurate channel information even in large Doppler frequency shift as well as poor channel environment,it can be good support the access of mobile terminal in the system.关键词
