- Abstract
- In this paper, a vector quantization - block constrained trellis coded quantization (VQ-BCTCQ) is presented to quantize line spectrum frequency (LSF) parameters of the wideband speech codec. Both the predictive structure and safety-net concept are combined into VQ-BCTCQ to develop the predictive VQ-BCTCQ. The performance of this quantization is compared with that of the linear predictive coding (LPC) vector quantizer used in the AMR-WB codec, and reductions in spectral distortion (SD) and encoding complexity are demonstrated.
