Abstract

La invención se refiere un sistema de la telecomunicación en el que la tierra se divide en zonas (26) dentro de las que las comunicaciones se llevan a cabo por un medio de transmisión y recepción situado en una nave espacial, como un satélite asignado para la comunicación para una pluralidad de zonas. El sistema consiste en asignar a zonas (26{sub,10}, 26{sub,11}, 26{sub,12}) de señales de una primera categoría (28) con un estado de polarización (P{sub,D}, P{sub,G}) y frecuencias portadoras (F{sub,1},F{sub,2}) tal que para dos zonas adyacentes de esta primera categoría se asignan señales con estados diferentes de polarización y frecuencias portadoras. En cada zona de una segunda categoría (30) se asignan todos los estados disponibles de polarización y frecuencias portadoras a las señales.
