Abstract
UN RECEPTOR QUE RECIBE (203) UN FLUJO DE SIMBOLOS DE INFORMACION (101) QUE PUEDE DETECTAR LA DISPONIBILIDAD DEL FLUJO DE SIMBOLOS DE INFORMACION RECIBIDO COMO SIGUE. AL RECIBIR EL FLUJO DE SIMBOLOS DE INFORMACION (101), EL RECEPTOR (203) SEPARA EL FLUJO DE SIMBOLOS DE INFORMACION EN UNA SECCION DESEADA Y EN UNA INDESEADA, DONDE LA PRIMERA ES EL FLUJO ORIGINALMENTE TRANSMITIDO DE SIMBOLOS DE INFORMACION, Y LA SEGUNDA SON LAS INTERFERENCIAS Y RUIDO (204). ENTRE LA SECCION DESEADA Y LA INDESEADA, SE PUEDE DETERMINAR LA DISPONIBILIDAD EN BASE AL INDICE DE LAS DOS SECCIONES.
