摘要
根据IEEE802.11a的前导结构和短训练序列的特点,利用短训练序列时域响应与输出序列进行互相关计算,由相关峰确定符号定时。仿真结果表明,该算法能有效克服噪声的影响,定时准确。
According to the preamble structure of IEEE802. 11a and the characters of short training symbols, the received output sequences and short training symbols are correlated. Mathematical methods for OFDM symbol timing can be confirmed from the correlating peak . The simulation result shows that this algorithm can overcome the influence of noise and get exact symbol timing.
