摘要

针对Alpha稳定分布噪声环境下时频混叠BPSK信号载频估计的性能退化问题，提出了基于循环相关熵谱的时频混叠BPSK信号载频估计方法，推导了BPSK信号在0频率处循环相关熵谱幅度切面上循环频率与载波频率之间的关系，并将此关系应用于载波频率估计中。这种基于循环相关熵谱载频估计方法，能够抑制脉冲噪声的影响，具有较好的估计性能，仿真实验证明了算法的有效性与顽健性。

Abstract

According to the performance degradation problem of the carrier frequency estimation method of time-frequency overlapped BPSK signals in Alpha-stable distribution noise

a novel carrier frequency estimation algorithm of the time-frequency overlapped BPSK signals based on the cyclic correntropy spectrum was proposed.The relationship between cyclic frequency and carrier frequency on the zero frequency section of the cyclic correntropy spectrum was deduced

which could be utilized for carrier frequency estimation.The proposed method can suppress the impulse noise and has better estimation performance than that of the contrastive methods.Simulation results are presented to demonstrate the effectiveness and robustness of the proposed method.
