Self-Calibration for Massive MIMO with Channel Reciprocity and Channel Estimation Errors
De Mi, Lei Zhang, Mehrdad Dianati +3
In time-division-duplexing (TDD) massive multiple-input multiple-output (MIMO) systems, channel reciprocity is exploited to overcome the overwhelming pilot training and the feedbac…
Peak-to-Average Power Ratio Analysis for OFDM-Based Mixed-Numerology Transmissions
Xiaoran Liu, Lei Zhang, Jun Xiong +3
In this paper, the probability distribution of the peak to average power ratio (PAPR) is analyzed for the mixed numerologies transmission based on orthogonal frequency division mul…
PAPR Reduction Using Iterative Clipping/Filtering and ADMM Approaches for OFDM-Based Mixed-Numerology Systems
Xiaoran Liu, Xiaoying Zhang, Lei Zhang +4
Mixed-numerology transmission is proposed to support a variety of communication scenarios with diverse requirements. However, as the orthogonal frequency division multiplexing (OFD…
RL-Based User Association and Resource Allocation for Multi-UAV enabled MEC
Liang Wang, Peiqiu Huang, Kezhi Wang +4
In this paper, multi-unmanned aerial vehicle (UAV) enabled mobile edge computing (MEC), i.e., UAVE is studied, where several UAVs are deployed as flying MEC platform to provide com…
