Abstract

Un método para implementar diversidad espacial utilizando interconexiones coaxil (712, 707) entre una cantidad de receptores (708), transmisores (713) yelementos de irradiacion (706, 704) en una disposicion de comunicaciones (700). La línea coaxil larga (707) usada para alimentar antenas receptoras asociadas(706) se usa para crear retardo de una senal (729) para implementar diversidad de conexion descendente. De modo similar, la línea coaxil larga (712) usada paraalimentar antenas transmisoras asociadas (704) se usa para crear retardo de una senal (760) para implementar diversidad de conexion ascendente. El método yaparato, en particular, incluyen también utilizacion de al menos uno de los elementos de irradiacion (706) para recibir una senal (709) y transmitir unaversion retardada de una senal (705) para ser transmitida.
