  2. 1. Interframe Quantization for Noisy Channels

    Author : Jan Lindén; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : The demand for efficient transmission and storage of, for example, speech signals poses high requirements on the development of signal compression techniques. This thesis deals with vector quantization (VQ) which is a powerful technique for signal compression. READ MORE
