Predictive vector quantization of wideband LSF using narrowband LSF for bandwidth scalable coders

A high-resolution study of resonant Auger decay processes in N2O after core electron excitation from terminal nitrogen, central nitrogen and oxygen atoms to the 3π LUMO

“…Preliminary calculations have ruled out the possibility of such a difference being due to different atomic populations or different geometries. In table 1, we report the N t 2p and O 2p populations of these two states in comparison with some of the outer valence states [38]. These populations do not change significantly in comparison with other states.…”

“…N t 2p and O 2p populations of the two 2 states with 2π −2 3π configurations and binding energies of 19.59 and 20.94 eV in comparison with other states, for three different geometries, obtained from SAC-CI calculations including up to triple excitations using a double zeta basis set[38].…”

Superwideband Bandwidth Extension Using Normalized MDCT Coefficients for Scalable Speech and Audio Coding

“…In other words, instead of using the side information, artificial bandwidth extension can estimate the higher band signal from the lower band signal by using a pattern recognition algorithm such as hidden Markov models (HMMs) [8] Gaussian mixture models (GMMs) [9] and [10][11][12][13][14][15]. While artificial bandwidth extension algorithms do not require any additional bits for sending the side information, their performance is somewhat restricted depending on the performance of the pattern recognition algorithm used in the extension, compared with the bandwidth extension using the side information [16][17][18][19][20]. Thus, an issue that arose in this bandwidth extension approach is how to improve the performance of the bandwidth extension algorithm with lower increase of the bitrate for the side information.…”
