Abstract

Una combinación de materiales de programas de banda ancha, tales como TV, servicios de comunicaciones digitales plus de todos los tipos, es difundida a una célula en la misma banda de frecuencias, tal como de 27,5 a 28,5 Ghz. La combinación 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 características de diversidad diferente de las de otros canales. En una realización, señales analógicas transmiten los servicios de banda ancha, preferiblemente utilizando modulación 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 polarización sea la misma. La polarizacon diferente de las señales digitales y de FM en la misma banda puede hacer posible la selección y la detección de la deseada de un espectro completo de señales digitales, o una cualquiera de las señales analógicas.A combination of broadband program materials, such as TV, digital communications services plus of all types, is broadcast 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 bandwidth that substantially exceeds the frequency band. At least some of the channels are transmitted with two different diversity characteristics from other channels. In one embodiment, analog signals transmit broadband services, preferably using FM modulation of the band. By selectively choosing carrier frequencies, 5 to 9 digital T-1 channels can be broadcast on each FM channel when the polarization is the same. Different polarization of digital and FM signals in the same band can make it possible to select and detect the desired one from a full spectrum of digital signals, or any one of the analog signals.
