Description
Zhen Li, Jinhui Hu, and Jian Xing design in 2026 the signal shaping for a wireless system that senses and communicates at once, aided by an active intelligent reflecting surface. Such surfaces, studded with tunable elements, can amplify and redirect radio waves, creating virtual line-of-sight paths for radar targets and phone users alike. The wrinkle is hardware imperfection at the base station transmitter, which injects distortion noise that couples with the surface own amplification noise.
The goal is to maximize radar signal quality while guaranteeing communication users their service levels and respecting two power budgets. Because the optimization problem is non-convex with coupled variables, the authors solve it by alternating: fixing some parts, optimizing others, and iterating. Future 6G base stations are expected to double as radar sensors, and designs that survive real hardware flaws, rather than assuming perfect radios, are the ones that will ship.
