Cen Lin Receives IEEE PIMRC Best Paper Award

Atlanta, GA

Cen Lin received the Best Paper Award at the IEEE International Symposium on Personal, Indoor, and Mobile Radio Communications, held September 2-5 in Washington, D.C. He is a Ph.D. student in the Georgia Tech School of Electrical and Computer Engineering (ECE).

Lin won the award for his paper entitled “Distance-Aware Multi-Carrier Indoor Terahertz Communications with Antenna Array Selection,” coauthored with his Ph.D. advisor and ECE Professor Geoffrey Li.

Terahertz (THz) band communications, with large unregulated frequency resources, is envisioned as a key technology by alleviating the spectrum limitation of current wireless systems. Lin's paper considers a future, indoor ultra-speed THz communication scenario, where the access point, equipped with multiple antenna subarrays, is deployed to serve multiple users with different distances. By exploiting the transmission windows in the THz band, a low-complexity, distance-aware multi-carrier transmission scheme is developed.

Specifically, Lin has proposed an adaptive beamforming strategy with antenna subarray selection that dynamically generates different numbers of beams for different users. Simulation results show that the THz system can effectively support tera-bit-per-second (Tbps) transmissions. This work builds a theoretical foundation for the THz band transmission.
