Beamforming for Centralized Wireless Sensor Network with Noisy Observation
This paper focuses on joint beamforming design towards maximizing mutual information (MI) in a coherent multiple access channel (MAC) wireless sensor network (WSN) with nodes equipped with multiple antennae. We consider the scenario where the same source signal is observed by all sensors, with each sensor having independent noisy observation and individual power constraint. All the sensors tran...
متن کاملPerformance Analysis of cooperative SWIPT System: Intelligent Reflecting Surface versus Decode-and-Forward
In this paper, we explore the impacts of utilizing intelligent reflecting surfaces (IRS) in a power-splitting based simultaneous wireless information and power transfer (PS-SWIPT) system and compare its performance with the traditional decode and forward relaying system. To analyze a more practical system, it is also assumed that the receiving nodes are subject to decoding cost, and they are on...
متن کاملUAV aided intelligent routing for ad-hoc wireless network in single-area theater
Large homogeneous ad hoc wireless networks have a problem: the bandwidth available to an mobile user decreases as the number of nodes in the network increases. Using the embedded ad-hoc networking mechanism, nodes are able to transport packets across the network in a multihop fashion. An embedded mobile backbone is dynamically constructed to form 2-level physical heterogeneous multihop wireless...
متن کاملAttention shifts the language network reflecting paradigm presentation
OBJECTIVES Functional magnetic resonance imaging (fMRI) is a reliable and non-invasive method with which to localize language function in pre-surgical planning. In clinical practice, visual stimulus presentation is often difficult or impossible, due to the patient's restricted language or attention abilities. Therefore, our aim was to investigate modality-specific differences in visual and audi...
متن کاملAdaptive Robust Null-Space Projection Beamforming Scheme for Secure Wireless Transmission with AN-aided Directional Modulation
In this work, an adaptive and robust null-space projection (AR-NSP) scheme is proposed for secure transmission with artificial noise (AN)-aided directional modulation (DM) in wireless networks. The proposed scheme is carried out in three steps. Firstly, the directions of arrival (DOAs) of the signals from the desired user and eavesdropper are estimated by the Root Multiple Signal Classificaiton...
