My research is focussed on wireless communication and sensing systems, primarily in the millimeter wave and THz frequency bands. These frequencies play an instrumental role in the evolution of the wireless landscape, as they facilitate vigorous frequency reuse and high-resolution sensing through the availability of large bandwidths and massive MIMO frontends.
The frequency reuse required for meeting the growing demand of smart devices and data-hungry applications is achieved by migrating to a picocellular infrastructure with a dense deployment of street-level access points, placed opportunistically on existing urban structures such as lamp posts, traffic lights, and walls. The small wavelength allows packing hundreds of antennas in small form factors to produce massive steerable arrays that form narrow pencil beams, limiting inter-cell and intra-cell interference while also providing a highly scalable solution for the backhaul problem that arises from rapid expansion. If realized, the picocellular infrastructure can also be leveraged for localization, environmental awareness, edge computing, and many other applications that emerge in this landscape.
Developing these emerging systems requires a broad understanding of hardware limitations, cost trade-offs, and channel characteristics to complement the signal processing and network optimization perspective. In collaboration with both hardware experts and signal processing and optimization researchers, I have tackled a wide variety of problems related to mm-wave communication and sensing, including backhaul network optimization, low-overhead user tracking, phase noise modeling, and scalable MIMO processing. Combined with my previous background on electromagnetics and wave propagation, this experience allows me to adopt the comprehensive approach necessary for developing future systems and realizing the many potentials of mm-wave and THz technology in mobile communication, localization, sensor networks, and IoT applications.
Going forward, my goal is to provide low-cost, scalable solutions for realizing the immense potential for communication throughput and sensing resolution via high bandwidth massive MIMO deployments. This involves tackling a wide range of problems from networking to signal processing and frontend design. Our experience shows that, while manufacturing wireless frontends is typically more challenging at mmWave and terahertz frequencies, a massive MIMO architecture allows relaxing many of the per-antenna (and per-RF chain) requirements, and there is much to be gained from joint hardware and system design. I therefore hope to pursue innovative architectures for MIMO communication and sensing and cross-layer design tools, complemented by scalable signal processing techniques that are robust to frontend impairments.
