An improved metric makes coarse timing synchronization better. Final timing synchronization based on complementary sequence pair is finished with timing field channel estimation accompanied.
帧检测与粗同步采用峰均比较低的随机序列,对度量函数的改进使粗同步获得更好的性能;精同步采用互补序列对,在完成精同步的同时并生成时域信道估计,互补序列对简化了计算量,但对频偏非常敏感,因此提出在时域信道估计前根据频偏估计值选择是否需要先纠正频偏。
