Abstract

SE PRESENTA UN DISPOSITIVO DECODIFICADOR DE DATOS QUE ELIMINA LA NECESIDAD DE CODIFICAR MEDIANTE UN DECODIFICADOR (38) PARA ESTIMAR LA PROPORCION DE ERRORES Y QUE PUEDE ESTIMAR LA PROPORCION DE ERRORES CON UNA ALTA PRECISION INCLUSO SI SE INCLUYE ALGUN ERROR. UN CALCULADOR DE ERRORES (39) CALCULA LA SUMA DE ERRORES AL CUADRADO EN BASE A LA SALIDA DE UN ECUALIZADOR (36). LA PROPORCION DE ERRORES REDUCIDA SE DETERMINA EN BASE A LA SUMA DE ERRORES, LA PROBABILIDAD SE DETERMINA EN BASE A LA PROPORCION ESTIMADA DE ERRORES, Y SE REALIZA LA DECODIFICACION POR DECISION DE "SOFTWARE" EN BASE A LA PROBABILIDAD Y A LA SALIDA DEL ECUALIZADOR.
