| Abstract: | By analyzing the characteristics of the common opened-loop PVQ (Predictive Vector Quantization) and closed-loop PVQ, half-closed loop PVQ, which combines the advantages of the two methods, is presented to get a better technique of prediction-VQ joint design. The validity of designation is testified by simulation. The result of test shows that half-closed loop PVQ has more flexible mode and better rebuilding quality. |
