Patent attributes
Methods and systems for improving communication using angle dithering are presented. Embodiments of the present invention provide increased throughput and robustness after link establishment by providing fast fading characteristics in environments dominated by slow fading. In particular, fast fading characteristics are induced by steering the transmitter and receiver antennas in optical and beyond line-of-sight troposcatter communication systems based on dither patterns. In non-line-of-sight (NLOS) communication systems, using coordinated dither patterns at the transmitter and receiver ensures that successive common scattering volumes become decorrelated, whereas in line-of-sight optical communication systems, the dither pattern is based on the tropospheric scintillation in free space traversed by the established link.
