This individual is an expert on the design, simulation, software implementation, and qualification of algorithms for signal detection & classification. An expert who understands the characteristics of a wide variety of terrestrial and satellite communications systems and radar signals and methods to detect these signals at low signal-to-noise ratios. This individual with work with other systems engineers and hardware/RF engineers to implement and verify spectrum sensing solutions in software defined radio platforms, implementing complex signal processing designs on embedded processors (e.g., ARMs, DSPs) that interface with an FPGA or ASIC. The candidate will also help determine how sensing results are used in an overall shared spectrum solution, implement chosen techniques, and conduct lab/field experiments to validate. To this end, the candidate will leverage knowledge of direction finding, geolocation, collaborative sensing, RF propagation, radio environment maps, and in-depth knowledge of various 3GPP and IEEE radio access technologies.
