A Signal Recovery Method for SNR Maximization of Specified Frequency
DING Minghui
Abstract：A signal recovery method for SNR maximization of specified frequency is proposed in this paper to improve the signal recovery method on time domain .This method uses a priori knowledge of the covariance matrix of noise in the mixed signal ,recovers the required signal and maximizes the SNR of specified frequency by linear combination of multi-chan-nel received signals .The method is derived and simulated compared with the signal recovery method on time domain in this paper .The result shows that the recovered signal has maximal SNR of specified frequency ,the method has an obviously good performance and good application value .
