Wide-band speech coding using kernel methods and bandwidth extension based on parametric stereo

A novel wide-band speech coding scheme is developed, in this paper, based on kernel methods and bandwidth extension. The KLMS algorithm, a kernelized version of the well-known LMS algorithm, is employed in the framework of the backward ADPCM technique for encoding the narrow-band part of the wide-band speech. Simulation results show that utilizing this… CONTINUE READING
