This shows how the phase lock loop can be designed and system parameter dendancy verified through simulation

all digital phase lock loop

锁相环跟踪主程序，里面有参数的详细说明,适合初学者理解锁相环的跟踪过程-simulation code for phase lock loop

Gardner位同步算法与锁相环的联合仿真程序.加入了时偏和频偏，能很好地锁定时偏和频偏，得到最佳采样输出。(Gardner bit synchronization algorithm and phase-locked loop joint simulation program, adding time offset and frequency offset, can well lock the bias and frequency offset, get the best sampling o
