Abstract
UNA COMBINACION DE MATERIALES DE PROGRAMAS DE BANDA ANCHA, TALES COMO TV, SERVICIOS DE COMUNICACIONES DIGITALES PLUS DE TODOS LOS TIPOS , ES DIFUNDIDA A UNA CELULA EN LA MISMA BANDA DE FRECUENCIAS, TAL COMO DE 27 , 5 A 28, 5 GHZ. LA COMBINACION DE TODOS LOS CANALES TRANSMITIDOS TIENE UNA ANCHURA DE BANDA COMBINADA QUE EXCEDE SUSTANCIALMENTE LA BANDA DE FRECUENCIAS. AL MENOS ALGUNOS DE LOS CANALES SON TRANSMITIDOS CON DOS CARACTERISTICAS DE DIVERSIDAD DIFERENTES DE LAS DE OTROS CANALES. EN UNA REALIZACION, SEÑALES ANALOGICAS TRANSMITEN LOS SERVICIOS DE BANDA ANCHA, PREFERIBLEMENTE UTIZANDO MODULACION DE FM CON DESVIACION DE ANCHURA, LLENANDO LOS CANALES DE FM LA BANDA. ELIGIENDO FRECUENCIAS DE PORTADORA SELECTIVAMENTE, PUEDEN DIFUNDIRSE ENTRE 5 Y 9 CANALES DIGITALES T - 1 EN CADA CANAL DE FM CUANDO LA POLARIZACION SEA LA MISMA. LA POLARIZACION DIFERENTE DE LAS SEÑALES DIGITALES Y DE FM EN LA MISMA BANDA PUEDE HACER POSIBLE LA SELECCION Y LA DETECCION DE LA DESEADA DE UN EXPECTRO COMPLETO DE SEÑALES DIGITALES, O UNA CUALQUIERA DE LAS SEÑALES ANALOGICAS.A COMBINATION OF BROADBAND PROGRAM MATERIALS, SUCH AS TV, PLUS DIGITAL COMMUNICATION SERVICES OF ALL TYPES, IS BROADCASTED TO A CELL IN THE SAME FREQUENCY BAND, SUCH AS 27, 5 TO 28, 5 GHZ. THE COMBINATION OF ALL TRANSMITTED CHANNELS HAS A COMBINED BAND WIDTH THAT SUBSTANTIALLY EXCEEDS THE FREQUENCY BAND. AT LEAST SOME OF THE CHANNELS ARE BROADCASTED WITH TWO DIVERSITY CHARACTERISTICS DIFFERENT FROM THOSE OF OTHER CHANNELS. IN AN EMBODIMENT, ANALOG SIGNALS TRANSMIT BROADBAND SERVICES, PREFERABLY USING FM MODULATION WITH WIDTH DEVIATION, FILLING THE FM CHANNELS WITH THE BAND. CHOOSING CARRIER FREQUENCIES SELECTIVELY, THEY CAN SPREAD BETWEEN 5 AND 9 DIGITAL CHANNELS T - 1 IN EACH FM CHANNEL WHEN THE POLARIZATION IS THE SAME. DIFFERENT POLARIZATION OF THE DIGITAL AND FM SIGNALS IN THE SAME BAND MAY MAKE POSSIBLE THE SELECTION AND DETECTION OF THE DESIRED FULL EXPECTRE OF DIGITAL SIGNALS, OR ANY OF THE ANALOG SIGNALS.
