Channel Coding for Gaussian Channels with Multifaceted Power Constraints
Adeel Mahmood, Aaron B. Wagner
Through refined asymptotic analysis based on the normal approximation, we study how higher-order coding performance depends on the mean power as well as on finer statistics of the…
Energy-Efficient Flat Precoding for MIMO Systems
Foad Sohrabi, Carl Nuzman, Jinfeng Du +2
This paper addresses the suboptimal energy efficiency of conventional digital precoding schemes in multiple-input multiple-output (MIMO) systems. Through an analysis of the power a…
Precoding-oriented Massive MIMO CSI Feedback Design
Fabrizio Carpi, Sivarama Venkatesan, Jinfeng Du +3
Downlink massive multiple-input multiple-output (MIMO) precoding algorithms in frequency division duplexing (FDD) systems rely on accurate channel state information (CSI) feedback…
Energy Efficient HARQ for Ultrareliability via Novel Outage Probability Bound and Geometric Programming
Kaiming Shen, Wei Yu, Xihan Chen +1
Hybrid automatic repeat 1 request (HARQ) is a key enabler for ultrareliable communications. This paper optimizes transmit power for the initial transmission and the subsequent retr…
Machine Learning-based Urban Canyon Path Loss Prediction using 28 GHz Manhattan Measurements
Ankit Gupta, Jinfeng Du, Dmitry Chizhik +2
Large bandwidth at mm-wave is crucial for 5G and beyond but the high path loss (PL) requires highly accurate PL prediction for network planning and optimization. Statistical models…
Universal Path Gain Laws for Common Wireless Communication Environments
Dmitry Chizhik, Jinfeng Du, Reinaldo A. Valenzuela
Simple and accurate expressions for path gain are derived from electromagnetic fundamentals in a wide variety of common environments, including Line-of-Sight (LOS) and Non-Line-of-…
