MIMO performance enhancement of MIMO arrays using PCS-based near-field optimization techniqueSpringer Science and Business Media LLC - Tập 66 - Trang 1-16 - 2023

Extensive efforts have been made in designing large multiple-input multiple-output (MIMO) arrays. Nevertheless, improvements in conventional antenna characteristics cannot ensure significant MIMO performance improvement in realistic multipath environments. Array decorrelation techniques have been proposed, achieving correlation reductions by either tilting the antenna beams or shifting the phase c...... hiện toàn bộ
Novel distributed UEP rateless coding scheme for data transmission in deep space networksSpringer Science and Business Media LLC - Tập 61 - Trang 1-10 - 2018
Shuang Wu, Dezhi Li, Zhenyong Wang, Qing Guo
In deep space data transmission systems, deep space networks can be constructed on different orbits, and the data from each orbit are always associated with the different reliability requirements. In this study, a novel UEP (unequal error protection) transmission scheme based on distributed LT codes is proposed in order to ensure that all the data can be transmitted according to their own reliabil...... hiện toàn bộ
An area based physical layer authentication framework to detect spoofing attacksSpringer Science and Business Media LLC - Tập 63 - Trang 1-14 - 2020
Na Li, Shida Xia, Xiaofeng Tao, Zhiyuan Zhang, Xiaohui Wang
In this paper, we propose an area-oriented authentication framework, which aims to provide a light-weight first authentication by reducing the complexity in acquiring and maintaining many different reference vectors as in the traditional one-by-one authentication framework. Under the proposed framework, we first derive the missing detection probability and the false alarm probability, respectively...... hiện toàn bộ
The stochastic semantics and verification for periodic control systemsSpringer Science and Business Media LLC - Tập 55 - Trang 2675-2693 - 2012
MengFei Yang, Zheng Wang, GeGuang Pu, ShengChao Qin, Bin Gu, JiFeng He
Periodic control systems (PCS) are widely used in the embedded industry like aerospace and automotive. Such systems usually run periodic tasks and respond to the external signals. Based on our previous work on Mode diagram modeling (MDM) notations for specifying the periodic control system, we present the stochastic semantics for MDM in this paper. The stochastic semantics of MDM is based on the M...... hiện toàn bộ
Simultaneous attack of a stationary target using multiple missiles: a consensus-based approachSpringer Science and Business Media LLC - Tập 60 - Trang 1-14 - 2017
Jialing Zhou, Jianying Yang, Zhongkui Li
This paper considers the simultaneous attack problem of multiple missiles against a stationary target. Built upon the classic proportional navigation structure, we propose a consensus-based approach to design the cooperative guidance law. Specifically, we present time-varying navigation ratios for the missiles, which exchange the time-to-go estimates between neighboring missiles via a communicatio...... hiện toàn bộ
