Due to the complicated signal structure, it is challenging to estimate sensing parameters such as delay, angle of arrival, and Doppler when joint communication and radar/radio sensing is applied in perceptive mobile networks. Radio sensing with signals compatible with a fifth...
简而言之,CRLB 是所有无偏估计量的方差的下限,它表明估计方差至少应与 Fisher 信息的倒数一样高。 B. Downlink Communication Model 预编码 线性预编码 二、dual-functional radar-communication (DFRC) 传输 A. Radar-Centric DFRC 设计以雷达为中心的 DFRC 波形 方法: B. Communication-Centric DFRC 重要的性能指...
初始波束发现 在通信的初始阶段,发射器和接收器并不知道彼此的最佳波束方向。为了找到这个方向,双方需要对所有可能的波束方向进行扫描。这一过程通常是通过**波束扫描(Beam Sweeping)**实现的。 发射端波束扫描:发射器通过一系列预定义的波束方向发送信号,接收器保持接收状态并测量每个波束方向的信号强度。 接收端波束扫...
In this paper, we use a reconfigurable intelligent surface (RIS) to enhance the radar sensing and communication capabilities of a mmWave dual function radar communication system. To simultaneously localize the target and to serve the user, we propose to adaptively partition the RIS by reserving sepa...
The historical development and current state-of-the-art of various joint wireless communication and radar sensing systems are reviewed and discussed in this study. Different kinds of systems are categorised according to their modulation waveforms and duplex schemes. Pros and cons of each category are...
This example simulates a JRC system using two different modulation schemes for generating a transmit waveform: PMCW and OFDM. The transmit waveforms are generated such that they can be used to sense radar targets and to carry communication data. The example shows how to simulate transmission, prop...

s radar spectrum is not nearly sufficient, especially as the number of components involved is bound to rise continuously. Various technologies designed to tackle this challenge are currently under discussion. Whereas ISAC (integrated sensing & communication) focuses on dedicated infrastructures for mobile...
This system enables a joint waveform for automotive radar and a potential mmWave vehicular communication system based on the mmWave consumer wireless local area network standard, allowing hardware reuse. To formulate an integrated framework of vehicle-to-vehicle communication and LRR, we make typical ...
