METHOD AND APPARATUS FOR QUANTIZING A SIGNAL IN A DIGITAL SYSTEM |
摘要 |
An input data signal (102) in a digital signal processing system gets adaptively quantized by performing a LMS error algorithm on a signal of transformed coefficients (113), determining paths of minimum error (202), and forming a three-dimensional matrix (206) representing these paths. Centroids are computed (208) based on the paths of minimum error (206), and these computed centroids are used as part of a next iteration to represent new quantization states and levels. |
