A priori SNR estimation and noise estimation for speech enhancement [PDF]
EURASIP Journal on Advances in Signal Processing, 2016 A priori signal-to-noise ratio (SNR) estimation and noise estimation are important for speech enhancement. In this paper, a novel modified decision-directed (DD) a priori SNR estimation approach based on single-frequency entropy, named DDBSE, is proposed.

SNR Estimation in Linear Systems With Gaussian Matrices [PDF]
IEEE Signal Processing Letters, 2017 This paper proposes a highly accurate algorithm to estimate the signal-to-noise ratio (SNR) for a linear system from a single realization of the received signal. We assume that the linear system has a Gaussian matrix with one sided left correlation.

Subspace Method-based Blind SNR Estimation for Communication between Orbiters in Mars Exploration
ITM Web of Conferences, 2017 In Mars exploration the effective time of communication between orbiters is short, and the relative distance and gesture between them change fast. The signal to noise ratio (SNR) estimation is required in receiver to change adaptively the data rate in ...

Pilot-Based Time Domain SNR Estimation for Broadcasting OFDM Systems
Journal of Computer Networks and Communications, 2018 The estimation of signal-to-noise ratio (SNR) is a major issue in wireless orthogonal frequency-division multiplexing (OFDM) system. In OFDM system, each frame starts with a preamble symbol that facilitates the SNR estimation. However, the performance of
