A Band Extension Technique for Narrow-Band Telephony Speech Based on Full Wave Rectification
SUMMARY This study investigates a band extension technique for narrow-band telephony speech. The proposed technique employs full wave rectification that nonlinearly generates high-band overtones from the low band. In order to improve the conventional technique, this study investigates a frame-by-frame gain control based on the estimation of gain parameter from narrow-band telephony speech. A su...
متن کاملA Lossless Steganography Technique for G.711 Telephony Speech
Steganography may be employed for secretly transmitting side information in order to improve the performance of signal processing such as packet loss concealment and band extension of telephony speech. The previous studies employ LSB replacement technique for embedding steganogram information into speech data. Instead of such a lossy steganography technique, this study proposes a lossless stega...
متن کاملNonlinear Modeling, Analysis and Design of an Active Antenna in S Frequency Band
An active antenna for transmitter application in S frequency band is designed and analyzed using harmonic balance technique which is based on the nonlinear model of active devices. In this active antenna, the amplifier is integrated with the radiator which is a rectangular patch antenna. This patch antenna is analyzed employing full-wave momentum method. By applying nonlinear model of transisto...
متن کاملA PCM coding noise reduction for ITU-t g.711.1
The ITU-T G.711.1 embedded wideband speech codec was approved by ITU-T in March 2008. This codec generates a bitstream comprised of three layers: a G.711 compatible core layer with noise shaping, a lower band enhancement layer and an MDCT-based higher band enhancement layer. It contains also an optional post-processing module called Appendix I designed to improve quality of the decoded speech i...
متن کاملNoise suppression based on extending a speech-dominated modulation band
Previous work on bandpass modulation filtering for noise suppression has resulted in unwanted perceptual artifacts and decreased speech clarity. Artifacts are introduced mainly due to half-wave rectification, which is employed to correct for negative power spectral values resultant from the filtering process. In this paper, modulation frequency estimation (i.e., bandwidth extension) is used to ...
