摘要：

A signal enhancement algorithm for SNR maximization of specified frequency range is proposed in this paper to improve the signal enhancement performance, which uses a priori knowledge of the covariance matrix of noise in the mixed signal, enhances the required signal and maximizes the SNR of specified frequency range by linear combination of multichannel received signals. The algorithm in this paper is derived and simulated compared with the signal enhancement algorithm of time domain, the result shows that the enhanced signal has maximal SNR of specified frequency range, and the algorithm has a obviously better performance and application value.
