Title: Interferer-tolerant RF/Millimeter-Wave Receivers in the Age of Ubiquitous Wireless

Wireless systems continue to drive and be driven by emerging data and sensing applications across billions of connected devices. Limitations in RF spectrum availability are motivating higher center frequencies at mm-wave, heterogenous cell sizes (macro, pico, femto), opportunistic carrier aggregation and increased spatial spectrum reuse. Wireless receivers must therefore simultaneously provide wide operating frequency, excellent sensitivity and interferer tolerance. In this talk, I will present research in the High-Speed Integrated Circuits Lab at Oregon State University on reconfigurable receivers that provide frequency-domain, code-domain and spatial-domain filtering to reject interferers. The talk will be focused on two extremes of integrated interferer-tolerant receiver design: ultra low-power receivers for pervasive internet-of-things applications and high-performance RF/mm-wave MIMO receivers for 5G and beyond-5G applications.
