Research: Developing an RF Front-End for Sub-Nyquist Radio
Compressed sensing radio receivers have the capability to revolutionize frequency-agile wireless communications, but they are barely beyond the realm of mathematical constructs. The Modulated Wideband Converter (MWC)—developed by Yonina Eldar at Technion —provides the frequency agility of other compressed sensing topologies, but is better adapted to wideband radio receivers. In its current incarnation, the MWC architecture suffers from severe sensitivity and blocking penalties relative to standard topologies .
I am researching circuit and system level optimizations that leverage the entire structure of the receiver so that it is competitive with standard receivers, while maintaining its inherent flexibility advantage.
Under the assumption that the frequency spectrum is sparse I seek to null the contribution of a small set of known blocking signals, thus enabling the MWC to perform in non-ideal real-world scenarios
