Abstract:
An improved mobile digital radio system is disclosed. A plurality of satellites and terrestrial repeaters transmit substantially identical information that is contained in an original time division multiplexed data stream. Each satellite transmits on a separate frequency band, and all terrestrial repeaters transmit on one shared frequency band. A mobile receiver simultaneously processes the frequency bands. The receiver selectively parses and concatenates a plurality of time division multiplexed data streams to substantially recompose the original data stream. The output may be a high fidelity audio signal, data for display, or a combination of audio and displayed data.
