Abstract: An SDARS receiver for use with at least two antennae, each of which receives bitstreams from a first satellite, bitstreams from a second satellite, and bitstreams from a terrestrial repeater, including demodulators configured to switch between demodulating bitstreams from the satellites and to switch between demodulating bitstreams from the terrestrial repeater, and a processor coupled to the demodulators, the processor being configured to switch the demodulators according to a variety of algorithms.

Abstract: A system optimizes terrestrial signal acquisition in a communication system by initially determining whether a first synchronization signal is available from a first ensemble, which has an associated first programmed content of a terrestrial signal. Next, when the first synchronization signal is not available from the first ensemble, the system switches to a second ensemble of the terrestrial signal to acquire a second synchronization signal, which is synchronized with the first synchronization signal. Finally, the system switches back to the first ensemble to retrieve the associated first programmed content.
