Subspace-Based SNR Estimation for Underwater Acoustic Communications

This paper proposes a signal-to-noise power ratio (SNR) estimation method for underwater acoustic environments that combines Hankel matrix transformation, singular value decomposition (SVD), and a Gaussian mixture model (GMM). Conventional approaches such as the second- and fourth-order moments, the time-domain power r...
