Title (EN) A METHOD AND APPARATUS FOR SPATIAL CHANNEL DECODING
(FR) PROCEDE ET APPAREIL DE DECODAGE DE CANAL SPATIAL
Abstract:
(EN) In the present invention, a spatial channel decoding method and apparatus thereof are proposed. This method comprises the steps of: (a) performing inverse spatial channel code (SCC) encoding process on a received SCC signal to obtain an inverse SCC encoded signal; (b) performing SCC encoding process on the inverse SCC encoded signal to obtain a SCC re-encoded signal; (c) calculating error between the received SCC signal and the SCC re-encoded signal; and (d) obtaining corresponding decoded signal based on the inverse SCC encoded signal and the error, according to the measured channel quality. By using this method and apparatus, the complexity of the spatial channel decoding can be reduced while a better system performance is kept.
(FR) L'invention concerne un procédé et un appareil de décodage de canal spatial. Le procédé consiste à: a) accomplir un processus de codage d'un code de canal spatial (SCC) inverse sur un signal SCC reçu afin d'obtenir un signal SCC inverse codé; b) accomplir un processus de codage SCC sur le signal SCC inverse codé afin d'obtenir un signal SCC recodé; c) calculer une erreur entre le signal SCC reçu et le signal SCC recodé; et d) obtenir un signal décodé correspondant basé sur le signal SCC inverse codé et l'erreur, selon la qualité du canal mesurée. La mise en oeuvre du procédé et de l'appareil de l'invention permet de réduire la complexité du décodage du canal spatial tout en conservant un meilleur rendement du système.
