16 kbit/s adaptive predictive coding of speech with adaptive postfiltering
D.J. Zarkadis, B.G. Evans · Electronics Letters · 1987
An adaptive predictive coder with backward adaptive short-term predictor is presented for operation at 16 kbit/s. Adaptive postfiltering is applied in the output of the decoder. By varying the degree of postfiltering the performance of the coder is evaluated both objectively and subjectively.
