Spatio-temporal Modeling for Massive and Sporadic Access
Yi Zhong, Guoqiang Mao, Xiaohu Ge +1
The vision for smart city imperiously appeals to the implementation of Internet-of-Things (IoT), some features of which, such as massive access and bursty short packet transmission…
Compressive Sensing Based Channel Estimation for Millimeter-Wave Full-Dimensional MIMO with Lens-Array
Ziwei Wan, Zhen Gao, Byonghyo Shim +3
Channel estimation (CE) for millimeter-wave (mmWave) lens-array suffers from prohibitive training overhead, whereas the state-of-the-art solutions require an extra complicated radi…
Principal Component Analysis Based Broadband Hybrid Precoding for Millimeter-Wave Massive MIMO Systems
Yiwei Sun, Zhen Gao, Hua Wang +4
Hybrid analog-digital precoding is challenging for broadband millimeter-wave (mmWave) massive MIMO systems, since the analog precoder is frequency-flat but the mmWave channels are…
A Topological Approach to Secure Message Dissemination in Vehicular Networks
Jieqiong Chen, Guoqiang Mao, Changle Li +1
Secure message dissemination is an important issue in vehicular networks, especially considering the vulnerability of vehicle to vehicle message dissemination to malicious attacks.…
STARIMA-based Traffic Prediction with Time-varying Lags
Peibo Duan, Guoqiang Mao, Shangbo Wang +2
Based on the observation that the correlation between observed traffic at two measurement points or traffic stations may be time-varying, attributable to the time-varying speed whi…
Interference Minimization in 5G Heterogeneous Networks
Tao Han, Guoqiang Mao, Qiang Li +2
In this paper, we focus on one of the representative 5G network scenarios, namely multi-tier heterogeneous cellular networks. User association is investigated in order to reduce th…
What Is the True Value of Dynamic TDD: A MAC Layer Perspective
Ming Ding, David Lopez Perez, Guoqiang Mao +1
Small cell networks (SCNs) are envisioned to embrace dynamic time division duplexing (TDD) in order to tailor downlink (DL)/uplink (UL) subframe resources to quick variations and b…
Uplink Performance Analysis of Dense Cellular Networks with LoS and NLoS Transmissions
Tian Ding, Ming Ding, Guoqiang Mao +3
In this paper, we analyse the coverage probability and the area spectral efficiency (ASE) for the uplink (UL) of dense small cell networks (SCNs) considering a practical path loss…
Performance Impact of Idle Mode Capability on Dense Small Cell Networks
Ming Ding, David Lopez-Perez, Guoqiang Mao +1
Very recent studies showed that in a fully loaded dense small cell network (SCN), the coverage probability performance will continuously decrease with the network densification. Su…
DNA-GA: A New Approach of Network Performance Analysis
Ming Ding, David Lopez Perez, Guoqiang Mao +1
In this paper, we propose a new approach of network performance analysis, which is based on our previous works on the deterministic network analysis using the Gaussian approximatio…
Performance Impact of LoS and NLoS Transmissions in Dense Cellular Networks
Ming Ding, Peng Wang, David Lopez-Perez +2
In this paper, we introduce a sophisticated path loss model incorporating both line-of-sight (LoS) and non-line-of-sight (NLoS) transmissions to study their impact on the performan…
Performance Analysis of Raptor Codes under Maximum-Likelihood (ML) Decoding
Peng Wang, Guoqiang Mao, Zihuai Lin +4
Raptor codes have been widely used in many multimedia broadcast/multicast applications. However, our understanding of Raptor codes is still incomplete due to the insufficient amoun…
Connectivity of Large Scale Networks: Distribution of Isolated Nodes
Guoqiang Mao, Brian DO Anderson
Connectivity is one of the most fundamental properties of wireless multi-hop networks. A network is said to be connected if there is a path between any pair of nodes. A convenient…
Connectivity of Large Scale Networks: Emergence of Unique Unbounded Component
Guoqiang Mao, Brian DO Anderson
This paper studies networks where all nodes are distributed on a unit square following a Poisson distribution with known density and a pair of node…
