4. 3. Quantization, Perception and Speech Coding

   Författare :Fredrik Nordén; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : This thesis is about compression of speech signals, a research area known as speech coding. The aim of a speech coder is to provide efficient digital representations of speech signals, required in digital transmission and storage systems. Contemporary speech coding algorithms typically separate the speech signal into sets of parameters. LÄS MER

5. 4. Interframe Quantization for Noisy Channels

   Författare :Jan Lindén; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : 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. LÄS MER
