专利名称：METHOD OF REDUCING QUANTIZATION NOISE
发明人：VAN DER VEEN, Minne,LEMMA, Aweke, N. 申请号：IB2005053378 申请日：20051014 公开号：WO06/0：There is described a system (10; 300) for processing an input signal (340) to generate a corresponding encoded output signal (380). The system (10; 300) includes a plurality of quantizing devices (30, 70; 350, 370) coupled in series, the system (10; 300 being configured in operation to reduce tandem quantization noise arising therein by: (a) analyzing the system (10; 300) to determine signal regions (290) in which tandem noise errors occur; and (b) modifying one or more earlier quantizing devices (30; 350) in the system (10; 300) with backward correction to reduce tandem noise arising therein from said determined signal regions (290), said one or more earlier quantizing devices (30; 350) not including a last quantizing device (70; 370) in series the system (10; 300).
