phase lock loop for coherent detection

％The phase locked loop(PLL),adjusts the phase of a local oscillator ％w.r.t the incoming modulated signal.In this way,the phase of the ％incoming signal is locked and the signal is demodulated.This scheme ％is used in PM and FM as well. ％We wi

This tutorial starts with a simple conceptual model of an analog Phase-Locked Loop (PLL). Through elaboration it ends at a model of an all digital and fixed-point phase-locked loop. The final model can serve a starting point for code generation (both

matlab下设计的pll锁相环，适用于电网电压锁相，不平衡锁相效果还没测试(pll phase lock with matlab simulink, haven't been tested for unbalanced situation)
