Abstract

Sistema de control automático de ganancia para sistema de transmisión digital OFDM multiusuario sobre red eléctrica. Cuenta con una pluralidad de equipos de usuario y un equipo de cabecera comunicados bidireccionalmente a través de la red eléctrica. Sus características esenciales son: un tratamiento portadora a portadora sobre las señales de emisión y sobre las señales en recepción y un control sobre la potencia de transmisión de los equipos. El sistema posibilita llegar al máximo número de usuarios, conseguir una máxima capacidad de transmisión, admitir señales provenientes de usuarios muy cercanos y muy lejanos, evitar que se produzcan desbordamientos, introducir el máximo de potencia media sobre el rango disponible para la comunicación y minimizar el número de bits necesarios para la conversión analógica/digital en recepción.
