Algorithms of Carrier Synchronization in Digital Communication Receiver
Ang Chen · Journal of Hunan Institute of Engineering · 2006
In this paper,base-band signal is returned by 2DPSK modulation signal.The algorithms of receiving and sending carrier frequency synchronization in digital communication receiver are suggested.The sampled mid-frequency signal(2DPSK) done with is Pseudo-orthogonal digital downconversion in DSP,and frequency difference of receiving and sending carrier by occurred signal.Though Kalman filter and digital phase-locked loop,base-band signal can be returned,can better solve carrier synchronization problem with the features of wide capture carrier range,fast synchronization track and little loop noise.
