Exposure-Aware Beamforming for mmWave Systems: From EM Theory to Thermal Compliance
Zihan Zhou, Ang Chen, Yunfei Chen +2
Electromagnetic (EM) exposure compliance has long been recognized as a crucial aspect of communications terminal designs. However, accurately assessing the impact of EM exposure fo…
Beyond Traditional Coherence Time: An Electromagnetic Perspective for Mobile Channels
Zihan Zhou, Li Chen, Ang Chen +1
Channel coherence time has been widely regarded as a critical parameter in the design of mobile systems. However, a prominent challenge lies in integrating electromagnetic (EM) pol…
A Data-Driven Adaptive Impedance Matching Method Robust to Parasitic Effects
Wendong Cheng, Li Chen, Weidong Wang
Adaptive impedance matching between antennas and radio frequency front-end (RFFE) power modules is essential for mobile communication systems. To address the matching performance d…
Revisiting MUSIC: A Finite-Precision Perspective
Yiming Fang, Li Chen, Ang Chen +1
The high computational complexity of the multiple signal classification (MUSIC) algorithm is mainly caused by the subspace decomposition and spectrum search, especially for frequen…
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.…
