Asymptotically Optimal and Near-optimal Aperiodic Quasi-Complementary Sequence Sets Based on Florentine Rectangles
Avik Ranjan Adhikary, Yanghe Feng, Zhengchun Zhou +1
Quasi-complementary sequence sets (QCSSs) can be seen as a generalized version of complete complementary codes (CCCs), which enables multicarrier communication systems to support m…
Massively Distributed Antenna Systems with Non-Ideal Optical Fiber Front-hauls: A Promising Technology for 6G Wireless Communication Systems
Lisu Yu, Jingxian Wu, Andong Zhou +2
Employing massively distributed antennas brings radio access points (RAPs) closer to users, thus enables aggressive spectrum reuse that can bridge gaps between the scarce spectrum…
Max-Min Optimal Beamforming for Cell-Free Massive MIMO
Andong Zhou, Jingxian Wu, Erik G. Larsson +1
This letter develops an optimum beamforming method for downlink transmissions in cell-free massive multiple-input multiple-output (MIMO) systems, which employ a massive number of d…
Quasi-Orthogonal Z-Complementary Pairs and Their Applications in Fully Polarimetric Radar Systems
Jiahuan Wang, Pingzhi Fan, Zhengchun Zhou +1
One objective of this paper is to propose a novel class of sequence pairs, called "Quasi-orthogonal Z-complementary pairs (QOZCPs)", each depicting Z-complementary property for the…
New Construction of Optimal Type-II Binary Z-Complementary Pairs
Zhi Gu, Zhengchun Zhou, Qi Wang +1
A pair of sequences is called a Z-complementary pair (ZCP) if it has zero aperiodic autocorrelation sums at each of the non-zero time-shifts within {a} certain region, called the z…
A New Path Division Multiple Access for the Massive MIMO-OTFS Networks
Muye Li, Shun Zhang, Feifei Gao +2
This paper focuses on a new path division multiple access (PDMA) for both uplink (UL) and downlink (DL) massive multiple-input multiple-output network over a high mobility scenario…
Low-PMEPR Preamble Sequence Design for Dynamic Spectrum Allocation in OFDMA Systems
Yajing Zhou, Zhengchun Zhou, Zilong Liu +2
Orthogonal Frequency Division Multiple Access (OFDMA) with Dynamic spectrum allocation (DSA) is able to provide a wide range of data rate requirements. This paper is focused on the…
New Constructions of Cross Z-Complementary Pairs
Avik Ranjan Adhikary, Zhengchun Zhou, Yang Yang +1
Spatial modulation (SM) is a new paradigm of multiple-input multiple-output (MIMO) systems, in which only one antenna at the transmitter is activated during each symbol period. Rec…
