Method for denoising audiosignals transmitted between telecommunication devices and method for testing it

For interference removal, the transmitted audio signals (1) are subjected to selective attenuation or amplification to a varied degree in each of constituent frequency bands. Further techniques employed, include frame autocorrelation coefficient calculation, the Levinson Durbin algorithm and linear...

Zusammenfassung:For interference removal, the transmitted audio signals (1) are subjected to selective attenuation or amplification to a varied degree in each of constituent frequency bands. Further techniques employed, include frame autocorrelation coefficient calculation, the Levinson Durbin algorithm and linear predictive coding.
