Abstract

Compressive sensing (CS) provides a mathematical platform for designing analog-to-digital converters (ADCs) that sample signals at sub-Nyquist rates. In particular, the framework espouses a linear sensing system coupled with a non-linear, iterative computational recovery algorithm. A central problem within this platform is the design of practical hardware systems that can be easily calibrated and coupled with computational recovery algorithms. In this paper, we propose a new CS-ADC that resolves some of the practical issues present in prior work. We dub this new system the polyphase random demodulator.
