Wireless Transmitters(无线发射器)研究综述
Wireless Transmitters 无线发射器 - Based on a prototype system previously used in pre-clinical research, we replaced the external cables of a 192-electrode iBCI with wireless transmitters and achieved high-resolution recording and decoding of broadband field potentials and spiking activity from people with paralysis. [1] GPS signals are not used only in positioning and navigation applications and services in transport and military, but, thanks to quite precise information about time, also for synchronization of world trade and synchronization of wireless transmitters. [2] This paper proposes a stand-alone program called FireLocator created by LabVIEW that can detect in real-time the geolocation and behavior of fires by superposition of detection areas through state-of-the-art multispectral infrared detectors using wireless transmitters and mathematical modeling algorithms at a very early stage with maximum spatial resolution. [3] Visible-light communication (VLC) is a short-range wireless access technology that deploys LEDs as wireless transmitters in addition to their primary task of illumination. [4] RF fingerprint recognition is an emerging technology for identifying specific hardware features of wireless transmitters. [5] The UV photodetector as sensor nodes can be integrated with wireless transmitters, constructing self-powered smog monitoring systems in IoT. [6] In this paper, we present a bandwidth enhancement technique for monolithic microwave integrated circuit (MMIC) Doherty power amplifiers (DPAs) in wireless transmitters. [7] Localization of wireless transmitters based on channel state information (CSI) fingerprinting finds widespread use in indoor as well as outdoor scenarios. [8] In recent years, the increasing number of wireless transmitters have begun to be gathered at a single point, creating new opportunities for passive radar systems. [9] In contrast to the conventional success probability, the meta distribution is the distribution of the conditional success probability (CSP), which is conditioned on the locations of the wireless transmitters. [10] Visible light communication (VLC) utilizes vehicle headlights as wireless transmitters and has emerged as a strong candidate for vehicle-to-vehicle (V2V) communications. [11] Power amplifier (PA) nonlinearity and in-phase and quadrature-phase (I/Q) imbalance are major concerns for wireless transmitters. [12] Using the channel state information (CSI) for physical-layer authentication is a promising concept in order to distinguish between wireless transmitters. [13] As the Internet of Things (IoT) continues to expand, there is a growing necessity for improved techniques to authenticate the identity of wireless transmitters. [14] Based on a prototype system previously used in pre-clinical research, we replaced the external cables of a 192-electrode iBCI with wireless transmitters and achieved high-resolution recording and decoding of broadband field potentials and spiking activity from people with paralysis. [15] Wireless transmitters are affected by various noise sources, each of which has a distinct impact on the signal constellation points. [16] Its general principle is to use an array of wireless transmitters (Txs) or receivers (Rxs) to focus and steer energy. [17] In this work, we analyze the maximum number of wireless transmitters (nodes) that can be scheduled subject to interference constraints across the nodes. [18] Taking inspiration from human communication, which utilizes inherent variations in the voice signatures to identify a certain speaker, we present RF-PUF: a deep neural network-based framework that allows real-time authentication of wireless nodes, using the effects of inherent process variation on RF properties of the wireless transmitters (Tx), detected through in-situ machine learning at the receiver (Rx) end. [19] The method is demonstrated by applying it to a practical high-frequency, high-power transistor called a HEMT (High-Electron Mobility Transistor) used in wireless transmitters. [20] However, power conditioning circuits are needed to maximize conversion efficiency and convert unstable input voltages, either DC or AC, to stable DC output voltages that can be used for sensors or wireless transmitters. [21] These small electronics include sensors, wireless transmitters, and/or actuators, etc. [22] With the anticipated industry-wide adoption of 5G, it is a matter of urgency to quantify and optimize the energy efficiency of 5G communication devices, and particularly their wireless transmitters. [23]基于之前用于临床前研究的原型系统，我们将 192 电极 iBCI 的外部电缆替换为无线发射器，并实现了对瘫痪患者的宽带场电位和尖峰活动的高分辨率记录和解码。 [1] GPS 信号不仅用于运输和军事领域的定位和导航应用和服务，而且由于时间信息非常精确，还用于世界贸易的同步和无线发射器的同步。 [2] 本文提出了一个由 LabVIEW 创建的名为 FireLocator 的独立程序，该程序可以通过使用无线发射器和数学建模算法的最先进的多光谱红外探测器叠加检测区域来实时检测火灾的地理位置和行为。具有最大空间分辨率的非常早期的阶段。 [3] 可见光通信 (VLC) 是一种短距离无线接入技术，除了照明的主要任务外，还将 LED 部署为无线发射器。 [4] 射频指纹识别是一种新兴技术，用于识别无线发射器的特定硬件特征。 [5] 紫外光电探测器作为传感器节点可以与无线发射器集成，在物联网中构建自供电烟雾监测系统。 [6] 在本文中，我们提出了一种用于无线发射器中单片微波集成电路 (MMIC) Doherty 功率放大器 (DPA) 的带宽增强技术。 [7] 基于信道状态信息 (CSI) 指纹识别的无线发射器定位在室内和室外场景中得到广泛应用。 [8] 近年来，越来越多的无线发射器开始集中在一个点上，为无源雷达系统创造了新的机遇。 [9] 与传统的成功概率相比，元分布是条件成功概率 (CSP) 的分布，它以无线发射器的位置为条件。 [10] 可见光通信 (VLC) 将车辆前照灯用作无线发射器，并已成为车对车 (V2V) 通信的有力候选者。 [11] 功率放大器 (PA) 非线性以及同相和正交相位 (I/Q) 不平衡是无线发射器的主要关注点。 [12] 使用信道状态信息 (CSI) 进行物理层认证是一个很有前途的概念，以便区分无线发射机。 [13] 随着物联网 (IoT) 的不断扩展，越来越需要改进技术来验证无线发射器的身份。 [14] 基于之前用于临床前研究的原型系统，我们将 192 电极 iBCI 的外部电缆替换为无线发射器，并实现了对瘫痪患者的宽带场电位和尖峰活动的高分辨率记录和解码。 [15] 无线发射器受到各种噪声源的影响，每种噪声源对信号星座点都有明显的影响。 [16] 它的一般原理是使用一系列无线发射器 (Txs) 或接收器 (Rxs) 来聚焦和控制能量。 [17] 在这项工作中，我们分析了可以在节点间受到干扰约束的情况下调度的无线发射器（节点）的最大数量。 [18] 从人类交流中汲取灵感，利用语音签名中的固有变化来识别某个说话者，我们提出了 RF-PUF：一种基于深度神经网络的框架，允许使用固有过程变化的影响对无线节点进行实时认证无线发射器 (Tx) 的射频特性，通过接收器 (Rx) 端的原位机器学习检测。 [19] 该方法通过将其应用于无线发射器中使用的称为 HEMT（高电子迁移率晶体管）的实用高频、高功率晶体管进行演示。 [20] 然而，需要功率调节电路来最大限度地提高转换效率并将不稳定的输入电压（直流或交流）转换为可用于传感器或无线发射器的稳定直流输出电压。 [21] 这些小型电子设备包括传感器、无线发射器和/或执行器等。 [22] 随着 5G 的预期在全行业范围内采用，量化和优化 5G 通信设备，尤其是其无线发射器的能效成为当务之急。 [23]
