4. An Echo Canceller with Frequency Dependent NLP Attenuation
University essay from Blekinge Tekniska Högskola/Institutionen för signalbehandlingAbstract : In this thesis, three different post-filtering algorithms for acoustic residual echo attenuation have been studied and simulated to see if the algorithms work in case of network echoes. The simulations were carried out using real recorded speech signals. The results are presented by different plots. READ MORE
