Abstract

In satellite communication systems, the received signal usually has the characteristics of high dynamic range and low signal-to-noise ratio(SNR), which leads to difficulty of carrier synchronization. The carrier estimation algorithm based on interpolation and frequency domain shifted average periodogram method could reduce the estimation error of frequency offset derivative, and increase the acquisition probability by bispectrum interpolation on the peak waveform of power spectrum output by parallel branches in the semi-symbol frequency domain shifted average periodogram method. The simulation results show that when bit SNR is 2.5 dB, compared with the semi-symbol frequency domain shifted average periodogram method, the estimation error of the frequency offset derivative can be reduced by 27% with only one interpolation calculation added. With the same accuracy requirement and parameter setting, compared with semi-symbol frequency domain shifted average periodogram method and zero-padding frequency domain shifted average periodogram method, the proposed algorithm reaches a higher probability of acquisition.
