摘　　要：采用自动链路建立(ALE)和基于FFT的联合帧同步与载波粗估计算法,经过卷积编码、矩阵交织、Walsh码扩频等及其反过程,针对物理层突发波形BW0的发送和接收进行了具体的仿真分析,并使用Matlab进行程序的编写,实验结果证实,系统改善了帧同步的性能,提高了估值的准确性。Using ALE and FFT-based joint frame synchronization and carrier rough estimation algorithm, through convolutional coding, matrix interleaving, Walsh code spread spectrum and its inverse process, the transmission and reception of burst wave BW0 in physical layer are simulated and analyzed in detail, and the program is compiled with MATLAB. The experimental results show that the system improves the performance of frame synchronization and improves the performance of frame synchronization. Accuracy of valuation.
