Title (EN) SIGNAL TRANSMITTING/RECEIVING APPARATUS AND METHOD FOR MULTI-INPUT MULTI-OUTPUT WIRELESS COMMUNICATION SYSTEM
(FR) APPAREIL D'EMISSION/RECEPTION DE SIGNAL ET PROCEDE DESTINE A UN SYSTEME DE COMMUNICATIONS SANS FIL MULTI-ENTREES MULTI-SORTIES
Abstract:
(EN) A signal transmitting/receiving apparatus and method for wireless communication system is disclosed. The transmitting apparatus in the present invention comprises a multi-path output selector for dividing the input information sequence into multiple paths, so as to obtain multiple shunt signals; and multiple transmitting units corresponding to the multiple shunt signals respectively. Each of the transmitting units includes a serial-to-parallel converter for serial-to-parallel converting of the shunt signals so as to obtain multiple block signals of a predetermined length; and a space-time block coder for space- time block coding the block signals so as to obtain multiple sets of coded block signals having orthogonality in the frequency domain. The corresponding receiving apparatus is also disclosed in the present invention. Compared with the prior art, the present invention is provided with higher coding rate and is more applicable to fast changing time-varying channels, and has less computation complexity.
(FR) L'invention concerne un appareil d'émission/réception de signal et un procédé destiné à un système de communications sans fil. L'appareil d'émission de l'invention comprend un sélecteur de sortie à trajets multiples permettant de diviser une séquence d'informations d'entrée en trajets multiples afin d'obtenir de multiples signaux de shunt; et de multiples unités d'émission correspondant respectivement aux multiples signaux de shunt. Chacune des unités d'émission comprend un convertisseur série-parallèle permettant d'effectuer une conversion série-parallèle des signaux de shunt afin d'obtenir des signaux de bloc multiples de longueur prédéterminée; et un codeur de blocs spatio-temporels codant les signaux de bloc afin d'obtenir de multiples ensembles de signaux de bloc codés présentant une orthogonalité dans un champ de fréquence. L'invention concerne également l'appareil de réception correspondant. Par rapport à l'état de la technique, l'invention permet un débit de codage plus élevé, s'applique plus facilement à des canaux à variation temporelle changeant rapidement et présente une complexité de calcul moindre.
