Abstract

Un sistema (110) de radio movil terrestre incluye una pluralidad de antenas (120) de recepcion para recibir señales de RF transmitidas a partir de unidades moviles. Cada antena (120) de recepcion está conectada a una matríz (133) de transformacion que divide cada señal de Rf recibida en un numero, N. de señales transformadas, cada señal transformada conteniendo una parte igual de nivel de energía, I/N, de cada señal de RF recibida. Cada señal transformada se proporciona a un amplificador (135) para amplificacion de la misma y, las señales transformadas amplificadas se proporcionan a una matríz (138) de inversion-transformacion que recombina las partes iguales de cada señal transformada amplificada en señales de RF recibidas amplificadas que se proporcionan a una seccion (125) de procesamiento de señal de RF. Las señales de RF amplificadas a continuacion se proporcionan a unidades (127) de canal de radio correspondientes.
