摘要
OFDM是一种新的高效的多载波调制技术,能够有效地对抗多径传播;但是,OFDM系统对定时和频偏很敏感。对一种具有802.16帧结构的OFDM系统定时同步和频率偏移估计算法进行了分析并通过MATLAB进行仿真实现。仿真结果表明算法适用于具有802.16帧结构的OFDM系统。
The OFDM (orthogonal frequency division multiplexing) is a new efficient multiple carrier modulation techniques immune to the multi-path interference. On the other hand the OFDM system is sensitive to the timing and carrier frequency offset. An algorithm to estimate the timing and carrier frequency offset of the 802.16 OFDM system is analyzed and simulated by using the Matlab. The results show that this algorithm can be applied to the 802.16 OFDM system.
