Mixed-Precision Quantization: Make the Best Use of Bits Where They Matter Most
Yiming Fang, Li Chen, Yunfei Chen +2
Mixed-precision quantization offers superior performance to fixed-precision quantization. It has been widely used in signal processing, communication systems, and machine learning.…
Near-Field Localization With Coprime Array
Hongqiang Cheng, Changsheng You, Cong Zhou
Large-aperture coprime arrays (CAs) are expected to achieve higher sensing resolution than conventional dense arrays (DAs), yet with lower hardware and energy cost. However, existi…
Intelligent Reflecting Surface-Aided Multiuser Communication: Co-design of Transmit Diversity and Active/Passive Precoding
Beixiong Zheng, Tiantian Ma, Jie Tang +3
Intelligent reflecting surface (IRS) has become a cost-effective solution for constructing a smart and adaptive radio environment. Most previous works on IRS have jointly designed…
Movable Antenna Enabled Symbiotic Radio Systems: An Opportunity for Mutualism
Chao Zhou, Bin Lyu, Changsheng You +1
In this letter, we propose a new movable antenna (MA) enabled symbiotic radio (SR) system that leverages the movement of MAs to maximize both the primary and secondary rates, there…
Near-Field Positioning and Attitude Sensing Based on Electromagnetic Propagation Modeling
Ang Chen, Li Chen, Yunfei Chen +2
Positioning and sensing over wireless networks are imperative for many emerging applications. However, since traditional wireless channel models over-simplify the user equipment (U…
