ABSTRACT:
A system (100) for combining satellite and terrestrial signals from spatially diverse antennas (102and104) includes a tuner (101) and at least first and second analog to digital converters (103, 105) for converting at least two among the plurality of satellite signals and the terrestrial signal to a first digital stream and a second digital stream. A switch arrangement (106, 102 126) selectively switches among the first digital stream and the second digital stream before demodulating the digital streams using a plurality of algorithms (112, 122, 130) that selectively uses respectively demodulated signals of the first digital stream and the second digital stream to control (114, 124, 132) the switch arrangement to provide a plurality of multiplexed signals (161, 162, 163) that are combined (134) to form a combined signal (170). The combined signal can then be forward error corrected (136).
