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…
Mobility and Coverage Evaluation of New Radio PDCCH for Point-to-Multipoint Scenario
Hongzhi Chen, De Mi, Belkacem Mouhouche +2
This paper provides the mobility and coverage evaluation of New Radio (NR) Physical Downlink Control Channel (PDCCH) for Point-to-Multipoint (PTM) use cases, e.g., eMBMS (evolved M…
Rate-Splitting for Multigroup Multicast Beamforming in Multicarrier Systems
Hongzhi Chen, De Mi, Zheng Chu +2
In this paper, we consider multigroup multicast transmissions with different types of service messages in an overloaded multicarrier system, where the number of transmitter antenna…
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…
Power-Imbalanced Low-Density Signatures (LDS) From Eisenstein Numbers
Zilong Liu, Pei Xiao, Zeina Mheich
As a special case of sparse code multiple access (SCMA), low-density signatures based code-division multiple access (LDS-CDMA) was widely believed to have worse error rate performa…
Low-PAPR Preamble Design for FBMC Systems
Zilong Liu, Pei Xiao, Su Hu
This paper presents a family of training preambles for offset QAM (OQAM) based filter-bank multi-carrier (FBMC) modulations with low peak-to-average power ratio (PAPR) property. We…
A Survey on Resource Allocation in Vehicular Networks
Md. Noor-A-Rahim, Zilong Liu, Haeyoung Lee +3
Vehicular networks, an enabling technology for Intelligent Transportation System (ITS), smart cities, and autonomous driving, can deliver numerous on-board data services, e.g., roa…
Cross Z-Complementary Pairs for Optimal Training in Spatial Modulation over Frequency Selective Channels
Zilong Liu, Ping Yang, Yong Liang Guan +1
The contributions of this paper are twofold: Firstly, we introduce a novel class of sequence pairs, called "cross Z-complementary pairs (CZCPs)", each displaying zero-correlation z…
Max-Min Rate of Cell-Free Massive MIMO Uplink with Optimal Uniform Quantization
Manijeh Bashar, Kanapathippillai Cumanan, Alister G. Burr +3
Cell-free Massive multiple-input multiple-output (MIMO) is considered, where distributed access points (APs) multiply the received signal by the conjugate of the estimated channel,…
On the Energy Efficiency of Limited-Backhaul Cell-Free Massive MIMO
Manijeh Bashar, Kanapathippillai Cumanan, Alister G. Burr +3
We investigate the energy efficiency performance of cell-free Massive multiple-input multiple-output (MIMO), where the access points (APs) are connected to a central processing uni…
Evaluation of Low Complexity Massive MIMO Techniques Under Realistic Channel Conditions
Manijeh Bashar, Alister G. Burr, Katsuyuki Haneda +4
A low complexity massive multiple-input multiple-output (MIMO) technique is studied with a geometry-based stochastic channel model, called COST 2100 model. We propose to exploit th…
