摘要 基于IEEE 802.16协议的WiMAX技术是目前BWA系统的热点之一,对于NLOS非视距传输环境,IEEE802.16d协议采用了OFDM技术作为调制方式。文章针对OFDM对定时和频偏敏感的问题进行了研究,给出了适用于IEEE 802.16d帧结构的帧同步和频偏估计算法,仿真结果表明该算法具有良好的性能。 WiMAX technology is one of the hot spots of BWA system,IEEE 802.16d protocol use OFDM as modulation technology on the NLOS conditions. This paper is concerned on frame synchronization and frenquency synchronization of OFDM,and propose the algorithms for IEEE 802.16d system.
