Abstract :
A novel approach to split-band systems for speech-coding applications is proposed and evaluated. This differs from the conventional filter-bank implementation of sub-band coding (SBC) in that a blocktransform method is employed to perform the spectral analysis and synthesis. It is shown that substantial savings in terms of system delay and complexity can be achieved using this approach.
