Develop synchronization, carrier and symbol recovery, equalization, and demodulation algorithms for both well-documented and poorly characterized waveforms, including frequency-hopped, spread-spectrum, and low-probability-of-intercept / low-probability-of-detection constructions. Recover payload bits and reconstruct higher-layer structure from tactical and strategic data links, including line-of-sight, beyond-line-of-sight, and satellite communications carriers (protected and commercial).
