Title (EN) METHOD AND APPARATUS FOR SIGNAL COMPRESSION AND DECOMPRESSION
(FR) PROCÉDÉ ET APPAREIL DE COMPRESSION ET DÉCOMPRESSION DE SIGNAUX
Abstract: front page image
(EN)In one embodiment, the method of compressing a digital signal includes reducing (S500) redundancies in the digital signal, scaling (S510) a block of samples output from the reducing step by a scaling factor, and quantizing (S520) the scaled samples to produce compressed samples. The digital signal being compressed may be a digital radio frequency signal.
(FR)Dans un mode de réalisation, le procédé de compression d'un signal numérique consiste à réduire (S500) des redondances dans le signal numérique, mettre à l'échelle (S510) un bloc d'échantillons, obtenus à l'issue de l'étape de réduction, au moyen d'un facteur d'échelle, et quantifier (S520) les échantillons mis à l'échelle afin de produire des échantillons comprimés. Le signal numérique comprimé peut être un signal radiofréquence numérique.
