    Abstract: A wideband receiver system comprises a wideband analog-to-digital converter (ADC) module and a digital frontend (DFE) module. The wideband ADC is configured to concurrently digitize a band of frequencies comprising a plurality of desired channels and a plurality of undesired channels. The DFE module is coupled to the digital in-phase and quadrature signals. The DFE module is configured to select the plurality of desired channels from the digitized band of frequencies, and generate an intermediate frequency (IF) signal comprising the selected plurality of desired channels and having a bandwidth that is less than a bandwidth of the band of frequencies, where the generation comprises frequency shifting of the selected plurality of desired channels. The IF signal may be a digital signal and the DFE is configured to output the IF signal via a serial or parallel interface.

    Abstract: A terrestrial receiver at a premises includes a plurality of antennas and a corresponding plurality of tuners. The terrestrial receiver receives terrestrial television signals via the plurality of antennas and the plurality of tuners and diversity combines a corresponding plurality of terrestrial television channels within the received terrestrial television signals, for example, based on control signals received from one or more customer premises equipment (CPE). The terrestrial receiver processes the diversity combined corresponding plurality of terrestrial television channels and communicates the processed and diversity combined corresponding plurality of terrestrial television channels to the one or more CPE. The diversity combined corresponding plurality of terrestrial television channels may be remodulated, and converted to corresponding analog signals prior to being communicated to the one or more CPE. The diversity combined corresponding plurality of terrestrial television channels may be demodulated and converted to intermediate frequency signals prior to being communicated to the one or more CPE.
