Abstract :
Trellis coded quantization (TCQ) is an efficient form of multidimensional quantization that achieves portions of the possible point density, space filling, and granular gains promised by vector quantization. For memoryless sources, the combination of TCQ and a suitable entropy code can provide performance within 0.5 dB of the rate-distortion limit
