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.

A method and system for maximizing throughput and minimizing latency in a communication system that supports heterogeneous links is presented. The communication system supports a primary link and an alternate link, and the method and system leverage the alternate link to reduce the overhead transmitted over the primary link, thereby increasing throughput and reducing end-to-end latency. The higher latency alternate link provides a delayed version of an information signal that corresponds to a portion of the information signal that is transmitted on the primary link. The received samples from the primary and alternate links may be used to equalize subsequent portions of the information signal received over the primary link, and may also be used for synchronization, timing recovery, DC offset removal, I/Q imbalance compensation, and frequency-offset estimation.
