Interleaved Training for Massive MIMO Downlink via Exploring Spatial Correlation
Cheng Zhang, Chang Liu, Yindi Jing +2
Interleaved training has been studied for single-user and multi-user massive MIMO downlink with either fully-digital or hybrid beamforming. However, the impact of channel correlati…
Joint Port Selection Based Channel Acquisition for FDD Cell-Free Massive MIMO
Cheng Zhang, Pengguang Du, Minjie Ding +2
In frequency division duplexing (FDD) cell-free massive MIMO, the acquisition of the channel state information (CSI) is very challenging because of the large overhead required for…
NOMA Design with Power-Outage Tradeoff for Two-User Systems
Zeyu Sun, Yindi Jing, Xinwei Yu
This letter proposes a modified non-orthogonal multiple-access (NOMA) scheme for systems with a multi-antenna base station (BS) and two single-antenna users, where NOMA transmissio…
Performance Analysis and Optimization of 3D Massive MIMO Multi-Pair Relaying with SWIPT
Samira Rahimian, Yindi Jing, Masoud Ardakani
In this paper, we study a massive multiple-input multiple-output (mMIMO) relay network where multiple source-destination pairs exchange information through a common relay equipped…
Decision Directed Channel Estimation Based on Deep Neural Network k-step Predictor for MIMO Communications in 5G
Mehrtash Mehrabi, Mostafa Mohammadkarimi, Masoud Ardakani +1
We consider the use of deep neural network (DNN) to develop a decision-directed (DD)-channel estimation (CE) algorithm for multiple-input multiple-output (MIMO)-space-time block co…
New Viewpoint and Algorithms for Water-Filling Solutions in Wireless Communications
Chengwen Xing, Yindi Jing, Shuai Wang +2
Water-filling solutions play an important role in the designs for wireless communications, e.g., transmit covariance matrix design. A traditional physical understanding is to use t…
