SYSTEM AND METHOD FOR WIDEBAND DIRECT SAMPLING AND BEAMFORMING USING COMPLEX ANALOG TO DIGITAL CONVERTER

摘要

A system comprising an radio frequency (RF) signal input; a plurality of time-skewed, undersampled analog to digital converters (ADCs); a plurality of complex finite input response (FIR) filters in parallel, wherein each complex FIR filter receives the output beam and/or band provided by the plurality of ADCs and generates a corresponding output beam of a given frequency.
