Efficient algorithms for fixed-rate entropy-coded vector quantization
In quantization of any source with a nonuniform probability density function, the entropy coding of the quantizer output can result in a substantial decrease in bit rate. A straight-forward entropy coding sche...

High Quality Low-Delay Speech Coding at 12 kb/s
For low-delay speech coders, the research challenge is to obtain higher compression rates while maintaining very high speech quality and meeting stringent low delay requirements. Such coders have applications ...
