Hi~~ It is a pitch-code gain quantization method It is a kind of 2-dim VQ y-axis is gc (represented by gbk1->gc bias) x-axis is gp (represented by gbk2->gp bias) if graphically expresed gc | . | | . ->gbk1 * <-unquantized (Gp,Gc) | . . | . | . . |. . . . . ->gbk2 | . . . . . . . . ---------------------------->gp So, gbk1 and gbk2 can cover the space Polt the gbk1 & gbk2 ...it is better to understand *********************************************************** ) Z Ѱ/ ſIMT2000ܸ Core/ DSP sub-part br /> Phone : 031-279-5451 H.P : 016-9530-5451 Dong-Won Lee Core Tech Research Team/ Telecommunication R&D center Information and Communication Business SAMSUNG ECELTRONICS CO., LTD. *************************************************************** |
