Verfahren und Vorrichtung für multiplexierte Vektorquantifizierung. |
摘要 |
A plurality of codebooks are provided each of which has a predetermined number of candidate vectors. A distortion between each input vector and an averaged vector of a set of candidate vectors, each selected from one of the codebooks, is calculated for all combinations of candidate vectors, and a combination of candidate vectors which provides the smallest distortion is determined. Codes representing the candidate vectors thus determined are multiplexed, thereafter being outputted. |
