Abstract

EL CAMPO DE LA INVENCION ES EL DE LA IGUALACION DE SEÑALES NUMERICAS, PARTICULARMENTE PARA COMBATIR LA INTERFERENCIA INTERSIMBOLO, POR EJEMPLO EN EL MARCO DE LA RADIOCOMUICACION CELULAR. LA INVENCION SE REFIERE A UN PROCESO DE IGUALACION DE UNA SEÑAL NUMERICA, DESTINADA PARA COMBATIR LA INTERFERENCIA INTERSIMBOLO, DEL TIPO QUE CONSISTE EN ASOCIAR A CADA MUESTRA RECIBIDA (XK) UN SIMBOLO ESTIMADO (EK), REPRESENTATIVO DEL SIMBOLO EMITIDO (XK), COMPRENDIENDO DICHO PROCESO UNA ETAPA ITERATIVA DE SUPRESION DE LA INTERFERENCIA INTERSIMBOLO, CADA ITERACION CONSISTE PARA CADA MUESTRA (XK) DE UN JUEGO DE MUESTRAS RECIBIDAS CUYO VALOR NO HA SIDO DETERMINADO DURANTE UNA ITERACION PRECEDENTE EN: RAL DE CONFIANZA Y, SI DICHA MUESTRA SOBREPASA UNOS DE DICHOS UMBRALES: ADO (EK) CUYO VALOR DEPENDE DE DICHO UMBRAL SOBREPASADO, DETERMINANDOSE ENTONCES EL VALOR DE DICHA MUESTRA (XK); (37) LA INTERFERENCIA INTERSIMBOLO PROVOCADA POR DICHO SIMBOLO ESTIMADO (EK) SOBRE LAS OTRAS MUESTRAS PERTENECIENTES A DICHO JUEGO DE MUESTRAS RECIBIDAS.
