An Enhanced Carrier Acquisition Algorithm for Low SNR and High Dynamic Signal

Almas Kaveh; Liu Rongke; Vahid Alipour Maralani
In deep space communications, the received signals have low SNR and high dynamic. The high dynamic characters cause a large Doppler frequency shift and frequency change rate so it makes to create problem in signal reception and processing. The traditional algorithm based on the maximum likelihood method for the carrier frequency acquisition with high dynamic and low SNR signal is analyzed. To solve this problem, an enhanced carrier acquisition algorithm with FFT and cyclic shifting accumulation by calculating periodogram, is proposed. There for by using this algorithm the signal frequency acquisition performance is enhanced. Also by the enhanced algorithm cyclically shifts the signal spectrum, the influence of the Doppler frequency change rate is eliminated, and then the captured carrier frequency accuracy is higher.
