Frequency-Offset Estimation of Satellite-Based AIS Signals
Abstract:
Aiming at satellite-based Automatic Identification System (AIS) signals, a blind carrier frequency-offset estimation method was investigated on AWGN channels. Estimation algorithm that is based on the autocorrelation function and a suitable smoothing function was deduced to estimate the frequency-offset. Simulation results show that its accuracy is better than the earlier methods and reduced the computational complexity.
