An algorithm for carrier frequency offset estimation in BPSK burst transmission

Abstract

In this paper, we propose a novel carrier frequency offset estimation algorithm in Binary Phase Shift Keying (BPSK) burst transmission based on pilot symbols and modulated data symbols. Its estimation range is large, about ±0.5 of the symbol rate. The simulation results show that this algorithm has low SNR threshold, and its estimation mean square error (MSE) is close to Cramer-Rao Lower Bound (CRLB). The algorithm's computational complexity is low and it is very suitable for practical application.
