Achievable-Rate Analysis of MISO Systems with Transmit-Side Multiport Matching Networks
Wendong Cheng, Li Chen, Weidong Wang
The paper derives an upper bound on the achievable data rate of a MISO transmitter that uses a multiport matching network, accounting for RF front‑end constraints, and proposes a p…
An Adaptive Antenna Impedance Matching Method via Deep Reinforcement Learning
Guoquan Zhang, Wendong Cheng, Weidong Wang +1
Adaptive impedance matching between antennas and radio frequency front-end modules is critical for maximizing power transmission efficiency in mobile communication systems. Convent…
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…
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…
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.…
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…
