| 摘 要： | 随着卫星导航信号的发展,BOC调制信号被广泛应用,然而,根据最新的研究发现,BOC信号在同步捕获方面还有许多新的挑战。考虑到副峰抑制方面现有方法的不足,本文研究BOC(2n,n)信号的特征并基于多通道相关函数的连接提出CCFR算法。通过理论研究和仿真模拟,CCFR算法可以消除第一副峰并且可以抑制其它次的副峰。且副峰抑制的性能方面优于现有的算法。

| Abstract: | With the development of satellite navigation signals, BOC modulation signals are widely used, however, according to the latest researches, BOC signals have faced new challenges in the synchronization acquisition.Considering the drawbacks of existing methods in side peaks suppression, researching the characters of BOC (2n,n) and putting forward CCFR(Cross correlation Function Reconstruction) base on the connection of multi channel correlation function. Through theoretical study and simulation, CCFR algorithm can eliminate the first side peaks and may inhibit other sub peak times. In addition, the performance of side peaks suppression is superior to existing algorithms. |
