| 摘 要： | 以FPGA为平台,提出了一种小波多速率调制同步系统的硬件实现方案。利用最大似然估计算法,采取帧同步与载波相位恢复相结合的方式,解决了小波调制在同步上对定时误差敏感等问题,同时也可以对假同步进行检测和纠正。仿真结果证明了该方案的可行性和有效性。

| Abstract: | Based on FPGA,a scheme of hardware implementation for the synchronization system of wavelet-based multirate modulation is proposed in this paper.A problem of false synchronization and high sensitivity to timing error,the carrier phase recovery was combined with frame synchronization on the basis of maximum likelihood(ML-)estimation,and the false synchronization can be detected and corrected as well.The simulation results indicate the availability and efficiency of our scheme. |
