IPC: G10L19/08
Filed: 2008-12-30
Abstract: La présente invention porte sur un nouveau système de codage audio qui peut coder aussi bien des signaux audio et des signaux vocaux à de faibles débits binaires. Un système de codage audio proposé comprend une unité de prédiction linéaire destinée à filtrer un signal d'entrée sur la base d'un filtre adaptatif; une unité de transformation destinée à transformer une trame du signal d'entrée filtré en un domaine de transformée; et une unité de quantification destinée à quantifier le signal de domaine de transformée. L'unité de quantification décide, sur la base de caractéristiques de signal d'entrée, de coder le signal de domaine de transformée avec un quantificateur basé sur un modèle ou un quantificateur non basé sur un modèle. De préférence, la décision est basée sur la taille de trame appliquée par l'unité de transformation.

IPC: H04L1/00
Filed: 2000-03-31
Abstract: In this invention, a channel estimation value of data symbols of a data channel is calculated by weighting and averaging pilot symbols in a parallel time multiplexing method. Also, a channel estimation value of data symbols during each data symbol interval is calculated by dividing data symbols in a slot into a plurality of data symbol intervals, selecting pilot symbols suitable for calculation of a channel estimation value of data symbols during each data symbol interval and weighting and averaging that pilot symbols. Also, a fading frequency is detected based on an inner product value of pilot symbols.  Weighting factors are changed based on the detected fading frequency. Also, a channel estimation value is calculated by weighting and averaging pilot signals using a plurality of weighting sequences. The calculated channel estimation value is used to demodulate received data. The output data with the highest quality is selected by judging reliability of these plurality of demodulated data. It is also possible to select some weighting sequences based on the result of the reliability judgment of the demodulated data for predetermined period of time. In this case, after the selection, demodulation is performed by using these selected weighting sequences only.
