Abstract: front page image
(EN)A method of multiple input-multiple output (MIMO) mode adaptive switch is disclosed in the present invention. The method determines the channel grade of current MIMO channel according to channel condition value of the current MIMO channel; calculates channel capacity of the current MIMO channel in a MIMO mode desired of switch; determines whether to perform MIMO mode switch and the intended mode of switch according to the determined channel grade and the calculated channel capacity. An apparatus of multiple input-multiple output (MIMO) mode adaptive switch is also disclosed in the present invention.
(FR)L'invention concerne un procédé de commutation adaptative en mode entrée multiple, sortie multiple (MIMO). Ce procédé consiste : à déterminer la catégorie du canal MIMO courant en fonction d'une valeur d'état dudit canal; à calculer la capacité du canal MIMO courant dans un mode MIMO de commutation souhaité; à déterminer si la commutation en mode MIMO doit être effectuée et à déterminer le mode de commutation souhaité en fonction de la catégorie de canal déterminée et de la capacité de canal calculée. L'invention concerne également un appareil de commutation adaptative en mode entrée multiple, sortie multiple (MIMO).
