摘要
基于CCSDS标准提出一种64 APSK信号载波频率偏移估计补偿算法,可在±1.4 MHz多普勒频偏范围内能正确补偿接收到的信号,消除无线卫星通信系统中多普勒效应对接收信号的影响。
Based on CCSDS standard,a 64APSK signal carrier frequency offset estimation compensation algorithm is proposed,which can correctly compensate the received signal within the range of±1.4MHz doppler frequency deviation,and eliminate the influence of doppler effect on the received signal in the wireless satellite communication system.
