Hybrid fluid-PIC (particle-in-cell) simulations aimed at a better understanding of the effect ion diffusion and viscosity on evolution Richtmyer–Meshkov instability (RMI) under high temperature density conditions are described. The use hybrid method, which treats ions as traditional particle-in-cell method electrons massless fluid, is motivated by difficulty handling material mixing in context commonly used fluid simulations. superdiffusive behavior observed plasma interface primarily...
This paper analyzes the fundamental limit of strategic semantic communication problem in which a transmitter obtains limited number indirect observations an intrinsic information source and can then influence receiver's decoding by sending messages over imperfect channel. The receiver have different distortion measures make rational decisions about their encoding strategies, respectively. decoder also some side (e.g., background knowledge and/or obtained from previous communications) to...

In theory, the capacity of a wireless network grows linearly with number users and antennas equipped at communication devices, hence large-scale MU-MIMO can scale up throughput. However, three main challenges are impeding implementation this promising technology in state-of-the-art WLANs. Firstly, current demands large high-priced RF chains. Secondly, access points (APs) overwhelmed by channel state information (CSI) feedback for nulling multi-user -antenna interference. Thirdly, lack...
Accurate channel state information (CSI) is a key requirement for massive multiple-input multiple-output to achieve multi-fold increases in throughput and secrecy rate. Consequently, an adversary targeting the sounding process has potential significantly degrade performance. In this paper, we first present model pilot distortion attack, simple but devastating jamming strategy which distorts access point's (AP's) CSI measurement of even single client leading denial service all clients...
Channel state information (CSI) has been proposed to enhance physical layer security by functioning as a shared secret between transmitter and receiver, because it decorrelates over half wavelength distances cannot be predicted based on locations of the receiver in rich scattering environments. Consequently, CSI was employed generate passwords, authenticate source packets, inject artificial noise thwart eavesdroppers. However, this paper, we present CSIsnoop, show that an attacker can infer...
Today's "white space" model of spectrum sharing applied in the UHF TV band allows channels that are not being used regionally by a broadcaster to be re-purposed for unlicensed-style secondary access 24 hour increments. Unfortunately, populated areas have few unused white space usage. Nonetheless, from viewer's perspective, Nielsen data show severe under-utilization this spectrum, with vast regions range transmitters having no active receivers on multiple even at peak viewing times. In paper,...
Summary Two‐tier heterogeneous networks, where the current cellular that is, macrocells, are overlapped with a large number of randomly distributed femtocells, can potentially bring significant benefits to spectral utilization and system capacity. In two‐tier network, cross‐tier interference needs be handled properly. Unlike downlink interference, uplink (UL) at femtocell caused by macrocell user equipment (MUE) has not been addressed sufficiently. When an MUE is located near coverage...
Massive multiple-input multiple-output (MIMO) is a promising technology in the next 5G communications. Directly merging massive MIMO with cloud radio access network (C-RAN) systems will cause disastrous link data overload, which greatly exceeds limitation of current 4G wireless standards. To solve this problem, we propose pre-filtering C-RAN architecture paper to compress inter connection rate between remote units (RRUs) and baseband (BBUs), based on structure linear detection algorithms...

Consequently, CSI was employed generate passwords, authenticate the source of packets, inject artificial noise thwart eavesdroppers. However, this paper, we present CSIsnoop, show that an attacker can infer multi-user WLAN, even if both channel sounding sequences from access point...
