Abstract:  The wireless spectrum crunch is driving the urgent need for shared spectrum access technologies to replace current, highly inefficient, fixed spectrum allocation policies. Further, security has become a critical component in future low-power wireless networks focused on connecting edge devices. The goal of my research is to develop energy-efficient systems for secure and spectrum-aware wireless communications. By working at the intersection of protocols, signal processing, device characteristics, and circuit design, I develop unique system solutions that would not be possible through isolated investigation. I focus on cross-layer optimization from circuits to protocols to drastically improve energy efficiency and obtain higher performance. In this talk, I will discuss a signal-model-driven compressed-sensing RF system that offers a novel and immensely more energy-efficient approach for the quick detection of interferers in a wideband spectrum. I develop a system-level approach that enables compressed-sensing systems to work in dynamic spectrum environments with changing sparsity conditions. Lastly, I will discuss a novel ultra-fast bit-level frequency-hopping system with data-driven channel selection for secure wireless communications.
