Abstract

Describes a speech coder based on the intersymbol interference coded quantizer (ICQ). The ICQ is a structured vector quantizer that can realize both boundary and granular gains for sources with memory. It is the quantization dual of the intersymbol interference coder-a transmission scheme for channels with memory. The authors have studied two different suboptimal ICQ codebook search algorithms for speech coding and find that the performance of the ICQ based speech coder is very good at rates over 13 kbps but degrades rapidly at lower rates
