Abstract

M�todo de decodificación esférica de señales de sistemas de comunicación de múltiples entradas y múltiples salidas (MIMO) de máxima verosimilitud.#En el que se aplica un método de cotas por minimizaci�n en caja que acelera la decodificación esférica y que comprende una etapa de preproceso y una etapa de búsqueda. Proporciona un nuevo test de factibilidad incluido en la etapa de búsqueda, en el que se obtienen señales scr{sub,i} que cuando no est�n en la caja obtiene la señal sck{sub,i}, lo que reduce y simplifica el número de minimizaciones, reduciendo el tiempo de computación y por tanto el coste temporal de la decodificación.#Además usa estas señales scr{sub,i} y/o sck{sub,i} para seleccionar una señal inicial x0 que se aplica en el método de minimizaci�n en caja, lo que también minimiza el coste temporal de las minimizaciones en caja.Method of spherical decoding of signals of communication systems of multiple inputs and multiple outputs (MIMO) of maximum likelihood. # In which a method of dimensions by minimization in box that accelerates spherical decoding and comprising a spherical decoding is applied. preprocess stage and a search stage. It provides a new feasibility test included in the search stage, in which scr {sub, i} signals are obtained that when they are not in the box obtains the sck {sub, i} signal, which reduces and simplifies the number of minimizations, reducing the computation time and therefore the temporary cost of decoding. # Also use these scr {sub, i} and / or sck {sub, i} signals to select an initial signal x0 that is applied in the cash minimization method, which also minimizes the temporary cost of cash minimizations.
