Abstract

The hub station (GS) of a network receives a multiplicity of signals in different frequency channels and possibly on different antennas (11-1 to 11-4). The individual signals to be demodulated may coexist in a radio frequency channel using FDMA, TDMA, or CDMA or other signal types or combinations thereof. The received frequency band is divided into subbands (12-1 to 12-5) which are all translated to baseband and distributed to the backplane of one or more demodulator chassis (14-1 to 14-6), each of which contain many demodulators. In this way, any demodulator may be connected to any signal. Relatively large segments of the input bandwidth are translated to baseband. These segments are then digitized and further band segmentation is performed digitally.
