| 摘 要： | 针对MIMO—OFDM系统的同步问题，在现有帧同步算法基础上进行改进，提出一种自适应门限的正交帧头判决方案，并将此方案应用于原同步算法的粗帧同步中。Matlab仿真结果表明，在存在码间干扰和多径衰落的无线信道中，该方案在不增加系统复杂度的前提下，可以提高帧同步的正确检测率和降低帧头的平均捕获时间，适用于高速移动通信系统。

| Abstract: | An adaptive threshold frame header decision scheme is proposed by improving the classical frame synchronization algorithm due to the question of synchronization in MIMO-OFDM systems,and this scheme is applied in the Coarse frame synchronization of original synchronization algorithm.Simulation results show that the scheme can enhance the correct examination rate of frame synchronization and decrease average acquisitive time under the disturbance of ISI and multi-diameters without increasing the complexity of... |
