Signal-to-Noise Ratio Estimation
Of the many measures that characterize the performance of a communication receiver, signal-to-noise ratio (SNR) is perhaps the most fundamental in that many of the other measures directly depend on its knowledge for their evaluation. In the design of receivers for autonomous operation, it is desirable that the estimation of SNR take place with as little known information as possible regarding o...
متن کاملEffect of signal to noise ratio on the speech perception ability of older adults
Background: Speech perception ability depends on auditory and extra-auditory elements. The signal-to-noise ratio (SNR) is an extra-auditory element that has an effect on the ability to normally follow speech and maintain a conversation. Speech in noise perception difficulty is a common complaint of the elderly. In this study, the importance of SNR magnitude as an extra-auditory effect on speech...
متن کاملSingle-image signal-to-noise ratio estimation.
A method for estimating the signal-to-noise ratio from a single image is presented in this paper. The autocorrelation-based technique requires that image details be correlated over distances of a few pixels, while the noise is assumed to be uncorrelated from pixel to pixel. The latter is shown to be a good approximation in the case of scanning electron microscope (SEM) images provided that the ...
متن کاملSignal-to-noise ratio adaptive post-filtering method for intelligibility enhancement of telephone speech.
Post-filtering can be utilized to improve the quality and intelligibility of telephone speech. Previous studies have shown that energy reallocation with a high-pass type filter works effectively in improving the intelligibility of speech in difficult noise conditions. The present study introduces a signal-to-noise ratio adaptive post-filtering method that utilizes energy reallocation to transfe...
متن کاملThe estimation of signal-to-noise ratio in continuous speech for disordered voices.
Presented is a method of estimating the signal-to-noise ratio ~SNR! of continuous utterances for patients with various types of voice disorders that ranged in severity of dysphonia from mild to severe. The SNR is estimated based on the residual that is left after systematically removing the shortand long-term correlations that exist in the speech signal. Results indicate that the SNR is consist...
