mobile digital radio system with space and time diversitu00e4tsmu00f6glichkeiten

摘要

An improved mobile digital radio system (26) is disclosed. A plurality of satellites (22) and terrestrial repeaters (24) transmit substantially identical information that is contained in an original time division multiplexed data stream (46). Each satellite (22) transmits on a separate frequency band, and all terrestrial repeaters (24) transmit on one shared frequency band. A mobile receiver (26; 70) 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 (46). The output may be a high fidelity audio signal, data for display, or a combination of audio and displayed data. IMAGE
