ABSTRACT:
The method of and the device for digital signal coding by vector quantization exploit representation of signal portions in a one-dimensional space for vector codebook generation and for coding for transmission and/or storage purposes. The n-dimensional sampling is transformed into coordinates in one-dimensional space preferably in accordance with Hilbert's curve.
