摘要
重点分析IEEE802.16e OFDMA物理层的关键部分,针对不同信道条件下,尤其是高车速条件下,为了克服无线信道的频率选择性衰落和较大的多普勒频偏带来的ICI(信道间干扰),接收机关键部分的设计。最后给出了完整的物理层平台在不同信道条件下的整体性能仿真结果。
The key mobility enhancements in IEEE 802. 16e PHY downlink are presented with the focus on the design of the receiver in various channel profiles, including frequency selective fading channel and especially in the high-speed vehicular environments, which introduces high Doppler spread and unavoidable intercarrier-interference （ICI）. The simulation results and corresponding analysis are also given.
