Abstract

Una estacion base que implementa una demanda repetida automatica de tapa fisica incluye un transmisor (38) y un receptor (52). El transmisor tiene un transmisor de capa fisica para recibir datos, formatea los datos recibidos en paquetes, transmitiendo los paquetes y retransmitiendo los paquetes en respuesta a la falla a recibir una confirmacion correspondiente para un paquete dado; un receptor (56) de confirmacion para recibir la confirmacion. correspondiente; y un controlador de modulacion adaptable y de codificacion para recolectar estadisticas de retransmision y ajustar los datos particulares de codificacion/modulacion, utilizando las estadisticas recolectadas. El receptor (52) tiene un receptor de capa fisica para desmodular los paquetes; un combinador/descodificador (50-1-50-n) para compensar, descodificar y detectar errores en los paquetes; y un generador de confirmacion para generar una confirmacion para cada paquete si ese paquete tiene una proporcion de errores aceptable.
