Performance Analysis for Training-Based Multi-Pair Two-Way Full-Duplex Relaying with Massive Antennas
Zhanzhan Zhang, Zhiyong Chen, Manyuan Shen +3
This paper considers a multi-pair two-way amplify-and-forward relaying system, where multiple pairs of full-duplex users are served via a full-duplex relay with massive antennas, a…
Cache-enabled Uplink Transmission in Wireless Small Cell Networks
Zhanzhan Zhang, Zhiyong Chen, Hao Feng +3
It is starting to become a big trend in the era of social networking that people produce and upload user-generated contents to Internet via wireless networks, bringing a significan…
A Mathematical Proof of the Superiority of NOMA Compared to Conventional OMA
Zhiyong Chen, Zhiguo Ding, Xuchu Dai +1
While existing works about non-orthogonal multiple access (NOMA) have indicated that NOMA can yield a significant performance gain over orthogonal multiple access (OMA) with fixed…
Optimization and Analysis of Probabilistic Caching in -tier Heterogeneous Networks
Kuikui Li, Chenchen Yang, Zhiyong Chen +1
In this paper, we study the probabilistic caching for an -tier wireless heterogeneous network (HetNet) using stochastic geometry. A general and tractable expression of the succe…
Opportunistic Channel Sharing in Stochastic Networks with Dynamic Traffic
Bin Xia, Yingbin Liu, Chenchen Yang +3
In this paper, we consider the stochastic network with dynamic traffic. The spatial distribution of access points (APs) and users are first modeled as mutually independent Poisson…
On Optimizing Hierarchical Modulation in AWGN channel
Baicen Xiao, Kexin Xiao, Zhiyong Chen +1
Hierarchical modulation (HM) is able to provide different levels of protection for data streams and achieve a rate region that cannot be realized by traditional orthogonal schemes,…
Delay Analysis and Optimization in Cache-enabled Multi-Cell Cooperative Networks
Yaping Sun, Zhiyong Chen, Hui Liu
Caching at the base stations (BSs) has been widely adopted to reduce the delivery delay and alleviate the backhaul traffic between BSs and the core network. In this paper, we consi…
The three primary colors of mobile systems
Hui Liu, Zhiyong Chen, Liang Qian
In this paper, we present the notion of "mobile 3C systems in which the "Communications", "Computing", and "Caching" (i.e., 3C) make up the three primary resources/funcationalties,…
