Abstract

Un sistema de comunicaciones que incluye: una pluralidad de transceptores portátiles de subsuperficie que incluyen, cada uno: una fuente de datos digital, un modulador acoplado a la fuente de datos digital, un amplificador de poder acoplado al modulador y una antena de bobina acoplada inductivamente al amplificador de poder; y un transceptor de base que incluye: una antena de núcleo de ferrita aislado eléctricamente para recibir señales magnéticas, una antena di-polar eléctrica para recibir ruidos ambientales, un cancelador de ruidos acoplado a la antena de núcleo de ferrita aislado y la antena di-polar eléctrica y que responde a la antena di-polar eléctrica para filtrar los ruidos de las señales recibidas vía la antena de núcleo de ferrita aislado, un demodulador acoplado al cancelador de ruidos y un decodificador acoplado al demodulador.
