Abstract
A system () for combining satellite and terrestrial signals from spatially diverse antennas (and) includes a tuner () and at least first and second analog to digital converters () 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 () selectively switches among the first digital stream and the second digital stream before demodulating the digital streams using a plurality of algorithms () that selectively uses respectively demodulated signals of the first digital stream and the second digital stream to control () the switch arrangement to provide a plurality of multiplexed signals () that are combined () to form a combined signal (). The combined signal can then be forward error corrected ().
