摘　　要：IEEE 802.16e协议为高速移动宽带无线接入系统制定了全球统一规范,文中简要介绍了WirelessMAN-OFDMA的下行子信道分配方式、时变多径衰落信道、基于导频的信道估计算法,并分析了上述信道估计算法在该协议下的仿真结果。IEEE 820.16e establishes a uniform criterion for high-speed mobile broadband wireless access. This paper introduces downlink subchannel allocation of WirelessMAN-OFDMA, time-variant muhipath fading channel, channel estimation based on pilot briefly, and finally a comparative performace based on IEEE802.16e is presented and analyzed in this paper.
