摘要
文章讨论了一种不受载波多普勒影响的Gardner位定时同步算法,并对该算法进行了MATLAB仿真与FPGA实现。基于内插的Gardner位定时算法不调整本地采样时钟,通过对输入的基带信号进行插值获得最佳采样时刻的采样值,从而实现数字码元同步。
In this paper, a kind of Gardner timing synchronization algorithm which is not affected by carrier doppler is discussed, and MATLAB simulation and FPGA implementation are carried out. Based on interpolated Gardner bit timing algorithm, the local sampling clock is not adjusted, and the sampling value of the optimal sampling time is obtained through the interpolation of the input baseband signal, so that the digital code element synchronization can be realized.
