Wideband Array Transmission - Waveforms and Phase Notching
Troposcatter communications can provide high data rates over long, beyond-line-of-sight distances without the use of relays. In this paper, we discuss the use of very wideband (multi-GHz) phased arrays with spatial processing in combination with waveform design to maximize data rates, while minimizing interference into other systems. We show how advanced signal processing techniques, based on methods used in commercial terrestrial wireless systems, can greatly enhance performance, allowing platform mobility while dynamically adapting to the troposcatter channel.
