An Achievability Bound for Variable-Length Stop-Feedback Coding over the Gaussian Channel
Ioannis Papoutsidakis, Robert J. Piechocki, Angela Doufexi
Feedback holds a pivotal role in practical communication schemes, even though it does not enhance channel capacity. Its main attribute includes adaptability in transmission that al…
Integer-Based Pattern Synthesis for Asymmetric Multi-Reflection RIS
Wei Wang, Angela Doufexi, Mark A Beach
This study delves into the radiation pattern synthesis of reconfigurable intelligent surfaces (RIS) / reflection metasurfaces. Through superimposing multiple single-reflection prof…
A DRL-based Reflection Enhancement Method for RIS-assisted Multi-receiver Communications
Wei Wang, Peizheng Li, Angela Doufexi +1
In reconfigurable intelligent surface (RIS)-assisted wireless communication systems, the pointing accuracy and intensity of reflections depend crucially on the 'profile,' represent…
Efficient Evaluation of the Probability of Error of Random Coding Ensembles
Ioannis Papoutsidakis, Angela Doufexi, Robert J. Piechocki
This paper presents an achievability bound that evaluates the exact probability of error of an ensemble of random codes that are decoded by a minimum distance decoder. Compared to…
Transmit Power Control for Indoor Small Cells: A Method Based on Federated Reinforcement Learning
Peizheng Li, Hakan Erdol, Keith Briggs +7
Setting the transmit power setting of 5G cells has been a long-term topic of discussion, as optimized power settings can help reduce interference and improve the quality of service…
Variational Autoencoder Assisted Neural Network Likelihood RSRP Prediction Model
Peizheng Li, Xiaoyang Wang, Robert Piechocki +3
Measuring customer experience on mobile data is of utmost importance for global mobile operators. The reference signal received power (RSRP) is one of the important indicators for…
