Abstract

This paper is focused on the synchronization algorithm of the blind demodulation in the case of unknown any prior information, which is aiming to meet the requirement of blind demodulation of MQAM signal when non-cooperative communication. After the signal passes through the Gaussian channel, in order to correct the time offset , the Gardner timing loop based on the FIR pre-filtering of self-noise reduction is studied and the carrier synchronization loop based on PD algorithm and DD algorithm switching principle is aiming to correct the phase offset. Through the simulation signal respectively on the timing and carrier loop simulation, the results show that the design Loop synchronization effect is good, in the project has a greater application value.
