Research on synchronization of all digital QPSK receiver

Jian Zhang

Abstract

Time synchronization and carrier synchronization are cruxes of receiver.The reliability and stability of traditional analog demodulation are bad,and adjustment is complex.A kind of time synchronization and carrier synchronization method is introduced in this paper,extraction of optimum sample-point and calculation of differential phase solution are used to achieve synchronization.All calculations of synchronization are completed by software,which has good flexibility.The results of computer simulation indicate that this method is feasible and suitable for the implementation in DSP.
