Description
Dahai Ni leads a seven-author team designing a receiver that keeps working when strong interference hits cheap hardware. Partially connected hybrid arrays cut cost by feeding many antennas into few radio chains, but low-resolution converters distort badly when a strong interferer arrives. Their receiver fights back in three stages that account for quantization from the start.
First, the array cycles through pseudo-random combining patterns, and a sparse fitting routine, corrected with a quantization noise model, reconstructs where interference power sits by angle. Second, analog combiners are tuned on that map to carve spatial nulls toward the interferers before conversion, respecting the hardware's coarse phase steps. Third, a robust digital combiner cleans up what remains. Simulations show better output signal quality than hybrid baselines across interference strengths, converter resolutions, phase settings, chain counts, and snapshot budgets.
