Research
Research at the Intelligent Radio and Integrated Systems (IRIS) Laboratory focuses on next-generation RF circuits and systems for wireless and satellite communications. We take a system-level approach that brings together digital signal processing, antenna arrays, RF front ends, and test and measurement to address the practical hardware limitations and interactions that ultimately determine system performance.
Research Areas
Hardware-aware digital signal processing
Modeling and mitigation techniques that account for practical hardware limitations and system-level interactions to improve beamforming-array transceiver performance.
Large-scale antenna arrays
Array design that jointly considers electromagnetic behavior, RF front-end non-idealities, and integrated sensing for DSP-assisted performance enhancement.
High-performance RF front ends
Design and linearization of high-efficiency RF front ends for ultra-wideband vector-modulated signal generation, including power amplifiers, frequency multipliers, and analog predistortion.
Test and measurement techniques
Signal processing and digital-twin methods that extend instrumentation capabilities for RF system characterization and enable realistic experimental emulation of large antenna arrays.
