ABSTRACT:
An improved sub-band speech coding system is provided by subdividing signals into a lower an higher subband, downsampling the lower subband before coding and coding the higher subband without downsampling. The decoder includes decoding and upsampling of the lower subband and decoding the higher subband and adding the higher subband to the lower subband.
