1. 程序的功能是:高速串行数据的恢复. 2. 其基本原理是：利用过采样，检测串行数据的边沿跳变，然后根据边沿提取处在数据相位正中央相邻的抽样值，将串行数据恢复过来。 3. 此程序是verilog 语言编写，用于xilinx virtexE 系列的FPGA-1. Program functions are: high-speed serial data recovery. 2. The basic principle is: the use of over-sampling to det

全数字锁相环实现位同步，通过3个触发器实现码元的边沿提取。基带码采用M序列仿真。-DPLL to achieve bit synchronization, achieved through three trigger symbol of the edge extraction. Baseband codes using M-sequence simulation.
