| Abstract: | A method based on FPGA for implementing timing recover algorithm is presented. The principles of the interpolation filter, timing error detector, loop filter and controller are analyzed. Through simulations on the Simulink plantform, the work procedures of various modules are understood and mastered. The four modules are also designed on the FPGA plant- form. Simulations are conducted on the Quartus II 9.1 platform. |
