摘要

本文提出了一种基于导频符号和调制数据符号的二进制相移键控(BPSK)突发传输载波频偏估计算法。其估计范围大，约为符号率的±0.5。仿真结果表明，该算法具有较低的信噪比阈值，估计均方误差(MSE)接近Cramer-Rao下限(CRLB)。该算法计算复杂度低，非常适合实际应用。

An algorithm for carrier frequency offset estimation in BPSK burst transmission

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.
