摘　　要：基于IEEE 802.11ad标准的60 GHz通信系统传输速率已经达到Gbps量级.针对该标准的突发通信特点,提出了一种高精度的帧同步检测方法.该方法利用前导序列良好的相关性,将接收信号与本地序列隔点进行相关运算获得相关峰,同时在峰值检测时设置动态判决门限.经仿真验证该算法不需要进行同步误差纠正,具有精度高,帧同步检测速度快的特点.The symbol transmission rate of 60 GHz communication system based on the IEEE802.11 ad standard has reached the Gbps magnitude. This paper proposes a novel frame synchronization detection algorithm for the burst communication system with high precision. The novel frame synchronization is accurately implemented using cross-related operation between local short training sequences and received signals with the good correlation of preamble. Simulations show that the algorithm has the advantages of high-precision, adaptive decision threshold and short synchronization time.
