Achievable-Rate Analysis of MISO Systems with Transmit-Side Multiport Matching Networks
Wendong Cheng, Li Chen, Weidong Wang
Characterizing communication performance under the physical constraints imposed by radio frequency front-end circuits is essential for bridging communication-theoretic analysis and…
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…
NN-Based Joint Mitigation of IQ Imbalance and PA Nonlinearity With Multiple States
Yundi Zhang, Wendong Cheng, Li Chen
Joint mitigation of IQ imbalance and PA nonlinearity is important for improving the performance of radio frequency (RF) transmitters. In this paper, we propose a new neural network…
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…
