摘要
介绍了基于OFDM的无线局域网标准IEEE 80 2 .1 1a的物理层相关OFDM参数和其基带IFFT实现原理 ,结合具体的分组结构 ,给出了其符号定时、载波频率偏移估计和信道估计方法 。
An overview is given for the new OFDM based wireless LAN standard IEEE 802.11a. Based on its packet structure, mathematical methods for OFDM symbol timing,carrier Frequency offset and channel estimation are proposed in this paper, which are also the critical technologies in a general OFDM system.[WT5HZ]
