COMMUNICATION UNIT, INTEGRATED CIRCUIT AND METHOD THEREFOR

摘要

A communication unit (100) comprises a predictive source encoder (134) capable of representing an input signal, wherein the predictive source encoder (134) comprises or is operably coupled to prediction memory, and quantization logic capable of representing the state of the prediction memory associated with the predictive source encoder. In addition, a communication unit comprises a predictive source decoder (134) capable of representing a received signal. The predictive source decoder (134) comprises or is operably coupled to logic arranged to obtain independent observations using both versions of the predictor memory state and combine them to obtain a Multi-Description coding gain (error free). Methods of encoding and decoding are also described.
