Sentence examples for spectrum enhancement from inspiring English sources

In this article, we investigate the effect of additive noise on the linear and logarithmic spectra of noise-corrupted utterances and provide a compensation scheme, called magnitude spectrum enhancement (MSE), to enhance the noise robustness of speech features.

It can be divided into linear filtering, spectrum enhancement, and feature enhancement.

Fig. 1 Illustration of three processing stages: beamforming log-magnitude spectrum enhancement, feature enhancement.

Next, detailed MSE procedures are described in Section 'The magnitude spectrum enhancement (MSE) approach'.

The proposed magnitude spectrum enhancement (MSE) approach uses the following two steps to create the new magnitude spectrum.

Singular value decomposition, power spectrum enhancement, and the least square fitting techniques are adopted to decouple and obtain the strain modes one by one.

Interestingly, no significant SERS spectra enhancement was observed with the SWS nanostructures although they also present quite regular but rough surfaces.

Examples of such applications include tuning of optical absorption spectra, enhancement of resonant luminescence of emitters embedded into the film, and tuning the wavelength range of optical nonlinearity.

The spectra enhancement achieved demonstrated that Au-diatom-based substrates could be considered good candidates as SERS substrates, but at the same time, their response was not completely reproducible in terms of intensity.

In the literature, many research works have been conceived on cooperative relay techniques in CRNs for spectrum efficiency enhancement.

The introduction of methoxy groups led to bathochromic shift of the absorption spectrum, and enhancement of the molar extinction coefficient of the dyes.
