Physical Layer Authentication for Non-Coherent Massive SIMO-Enabled Industrial IoT Communications

IEEE Transactions on Information Forensics and Security (2020)

Zhifang Gu He Chen Pingping Xu Yonghui Li Branka Vucetic

Achieving ultra-reliable, low-latency and secure communications is essential for realizing the industrial Internet of Things (IIoT). Non-coherent massive multiple-input multiple-output (MIMO) is one of promising techniques to fulfill ultra-reliable and low-latency requirements. In addition, physical layer authentication (PLA) technology is particularly suitable for secure IIoT communications thanks to its low-latency attribute. A PLA method for non-coherent massive single-input multiple-output (SIMO) IIoT communication systems is proposed in this paper. This method realizes PLA by embedding an authentication signal (tag) into a message signal, referred to as "message-based tag embedding". It is different from traditional PLA methods utilizing uniform power tags. We design the optimal tag embedding and optimize the power allocation between the message and tag signals to characterize the trade-off between the message and tag error performance. Numerical results show that the proposed message-based tag embedding PLA method is more accurate than the traditional uniform tag embedding method which has an unavoidable tag error floor close to 10%.

A merger weight-based synchronization algorithm for WiMedia MAC

Ting Zuo Pingping Xu

WiMeida MAC, coupled with physical layer based on UWB technology, is now widely applied in high data rate wireless personal area networks (WPANs). Because the transmission with the UWB technology is restricted to a short range, multiple piconets may exist in a network at the same time. We investigate problems related to beacon collisions and data communication disruptions when piconets interfere into each other due to changes in propagation environment, moving devices, or other effects. For the purpose of resolving this problem and minimizing the cost, we propose a merger weight-based synchronization algorithm. The performance of the algorithm is simulated and compared with coordinated merger of BPs scheme provided in WiMedia MAC, and results show that there is room for further improvement over the current synchronization algorithm in WiMedia MAC.

Sparse Array of Sub-surface Aided Anti-blockage mmWave Communication Systems

GLOBECOM 2022 - 2022 IEEE Global Communications Conference (2020)

Weicong Chen Xi Yang Shi Jin Pingping Xu

Recently, reconfigurable intelligent surfaces (RISs) have drawn intensive attention to enhance the coverage of millimeter wave (mmWave) communication systems. However, existing works mainly consider the RIS as a whole uniform plane, which may be unrealistic to be installed on the facade of buildings when the RIS is extreme large. To address this problem, in this paper, we propose a sparse array of sub-surface (SAoS) architecture for RIS, which contains several rectangle shaped sub-surfaces termed as RIS tiles that can be sparsely deployed. An approximated ergodic spectral efficiency of the SAoS aided system is derived and the performance impact of the SAoS design is evaluated. Based on the approximated ergodic spectral efficiency, we obtain an optimal reflection coefficient design for each RIS tile. Analytical results show that the received signal-to-noise ratios can grow quadratically and linearly to the number of RIS elements under strong and weak LoS scenarios, respectively. Furthermore, we consider the visible region (VR) phenomenon in the SAoS aided mmWave system and find that the optimal distance between RIS tiles is supposed to yield a total SAoS VR nearly covering the whole blind coverage area. The numerical results verify the tightness of the approximated ergodic spectral efficiency and demonstrate the great system performance.

Modeling Channel Switching and Contention Control in Vehicular Networks

IEEE Access (2017)

Guilu Wu Ren Ping Liu Wei Ni Gordon J. Sutton Pingping Xu

In vehicular networks, multi-channel operation standard IEEE 1609.4 is designed for vehicular communications across multiple channels. It has been revealed that such multi-channel operations may result in high contention in vehicular communications. However, existing analytical models are unable to capture the dynamic characteristic during channel switching. We develop a novel Markov model that takes into account the dynamic contention behavior during channel switching. In particular, our model reveals the high contention caused by the burst arrivals, which are the results of multi-channel operations. To combat such performance decline, we propose two solutions, a centralized equal-spaced algorithm and a distributed random-spaced algorithm. The key idea is to disperse the burst packet arrivals across the available timeframe in order to alleviate contention. Our model, validated by simulations, accurately characterizes the high contention caused by multi-channel operations. Our results demonstrate our proposed solutions can effectively mitigate packet collision, enhance reliability, and improve system throughput during the multichannel operations.

PAPR reduction of FBMC-OQAM signals based on cuckoo search optimization algorithm

2022 IEEE International Conference on Signal Processing, Communications and Computing (ICSPCC) (2017)

Yan Yang Pingping Xu

In recent years one of key technologies of 5G, the filter bank multicarrier with offset quadrature amplitude modulation (FBMC-OQAM) has been studied widely by many researchers. In this paper, the problem of peak-to-average power ratio (PAPR) reduction is considered for FBMC-OQAM systems using cuckoo search optimization algorithm(CSOA). Because of overlapping structure of FBMC-OQAM signals the CSOA is not directly applying to FBMC-OQAM systems. It is used for multiblock joint of system when the transmit sequences are divided into partial transmit sequence (PTS) for PAPR reduction. In the combinatorial search space, stochastic and metaheuristic can be applied to solve non-deterministic polynomial hard (NP-hard). CSOA can be guaranteed to the optimal solution without exhaustive search. It is shown that the PAPR of FBMC-OQAM systems is reduced by CSOA in theoretical analysis and simulations illustrations. Complementary cumulative distribution function (CCDF)of in PAPR can be obtained under the same parameters of subcarriers number and modulation type.

Novel multi-path routing scheme for UWB Ad hoc network

Journal of China Institute of Communications (2005)

Pingping Xu Yang Cai-yu Song Shu-qing Guangguo Bi

The routing protocols play an important role for ad hoc networks performance.As some problems with DSR,SMR,and AMR protocols were analyzed,a new routing protocol suitable for UWB Ad hoc networks was proposed in this paper.The new routing protocol utilize an act of orientation of UWB and tries to get sufficient route information and decrease the network load caused by route discovery at the same time.Simulation results show that the routing load of the new protocol is lower and throughput is higher than that of DSR.While the node's mobility increases,these advantages become more obvious.

Pingping Xu

The dynamic frequency selection (DFS) is an impelling means to solve the question of real-time optimization in channel assignment. Aiming at WLAN/WPAN and other small area wireless multimedia communications systems, the simulated annealing algorithm is firstly applied to the DFS algorithm in this paper. The complete process in the system of WLAN/WPAN is described. As a practical example, the simulation of HiperLAN/2 system is given. Comparing to other algorithms, the result of simulation indicates that the new algorithm realizes the combination optimization of whole system, overcomes some weakness of the current algorithm such as continual transition, unsteady and so on. The algorithm can satisfy request of WLAN/WPAN in complex communications environment and ensure quality of service (QoS) of system.

A novel link scheduling strategy for concurrent transmission in mmWave WPANs based on beamforming information

2022 IEEE Wireless Communications and Networking Conference (WCNC) (2014)

Pingping Xu Hongyun Chu

This paper proposes a novel link scheduling strategy for concurrent transmission in millimeter-wave (mmWave) wireless personal area networks (WPANs) based on beamforming information. Firstly, we consider the signal-to-interference-plus noise ratio (SINR) as the links coexistence criterion, and derive the interference model with different antenna configurations. Then we describe how to use the beamforming information to calculate the SINR for concurrent transmission in a common service period (SP). A first-request-first-scheduling (FRFS) SINR based algorithm is applied to schedule links in SPs. Simulation results show that the proposed link scheduling scheme performs well and achieves a higher spatial multiplexing gain.
