This letter presents a new mixed-order MUSIC algorithm for far-field and near-field sources localization using sparse symmetric array. By exploiting the special array geometry, proposed constructs cumulant matrix to estimate directions of arrival (DOAs) both conventional method. With estimated DOAs covariance array, are identified range parameters also obtained by defining spectrum. Compared with traditional algorithms, has moderate computation complexity, provides higher resolution,...
In this letter, a novel mixed sources localization method based on sparse signal reconstruction is presented, which can efficiently estimate direction-of-arrival (DOA) and range parameters of near-field far-field sources. By constructing the cumulant domain data array only related to DOA sources, we obtain estimation all using weighted <i xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">l</i> <sub xmlns:xlink="http://www.w3.org/1999/xlink">1</sub>...
It is expected that the future intelligent transportation system will be endowed with sensing ability to cope complex road environment. Therefore, integrated and communications (ISAC) can complement development of transportation. In this work, a novel reconfigurable surface (RIS)-aided ISAC investigated, in which an RIS reflects signals vehicle target user by creating directional path enhance communication performance. We are interested joint robust design transmitted beamformer at...
Near-field (NF) localization is a key research topic in various applications, including autonomous vehicles, real-time tracking, target monitoring, etc. However, the traditional NF methods mostly rely on line-of-sight (LOS) condition, and performance may suffer degradation when there are lacking LOS paths. In this paper, we introduce promising technology named reconfigurable intelligent surface (RIS) to resolve problem investigate RSS-based algorithms. To be specific, apply RIS construct...
This paper explores the near-field regional target localization problem with reconfigurable intelligent surface (RIS) assisted system. Traditional strategies typically estimate position of through line-of-sight (LOS) signals transmitted from anchor node. In practice, accurate location estimation is a challenging issue when LOS link between node and may be unavailable due to obstacle. To this end, investigates possibility confirm consisted in an area interest (AOI) by retrieving information...
Gaussian process model for vector-valued function has been shown to be useful multi-output prediction. The existing method this is re-formulate the matrix-variate distribution as a multivariate normal distribution. Although it effective in many cases, re-formulation not always workable and difficult apply other distributions because all can transformed respective distributions, such case Student$-t$ In paper, we propose unified framework which used only introduce novel regression (MV-TPR)...
In this letter, near-field sources localization in partly calibrated uniform linear arrays (ULAs) with unknown gains and phases is considered. The existing methods generally assume that the array sensor perfectly calibrated, i.e., error of not However, practical applications, problem exists performance these algorithms may decay under array. Aiming to solve problem, we propose a new method estimate directions arrival (DOAs) ranges ULAs. proposed include two steps. First, by making use...
Empathetic dialogue is a human-like behavior that requires the perception of both affective factors (e.g., emotion status) and cognitive cause emotion). Besides concerning status in early work, latest approaches study causes empathetic dialogue. These focus on understanding duplicating context to show empathy for speaker. However, instead only repeating contextual causes, real empathic response often demonstrate logical emotion-centered transition from those responses. In this we propose an...
Multi-target tracking (MTT) plays a significant role in intelligent transportation systems, serving as an enabling technology for applications such self-driving, surveillance, and navigation. To enhance the MTT performance, unmanned aerial vehicles (UAVs) have emerged effective assistants to MIMO radar system, due their advantages of high flexibility, controllable deployment cost-effectiveness. Towards this end, work investigates multi-UAV-enabled which each UAV is equipped with unit...
In this paper, a reconfigurable architecture for symmetric ciphers is presented. The InterConnection Tree between Rows (ICTR) reduces the complexity of interconnection based on data locality and finally decreases area overhead. Hierarchical Context Organization (HCO) scheme uses an index-based configuration mechanism to avoid duplication contexts accelerate dynamic configuration. Experimental results show that capable implementing most ciphers, such as AES, Camellia, DES, SHACAL-1, SMS4,...
Analog mixed-signal (AMS) receivers for 50+Gb/s PAM-4 offer lower power than ADC-DSP [1]-[3]. Those using DFEs [2]-[3] suffer from relatively high consumption due to the large number of latches needed in speculative DFEs. Better efficiency can be achieved only a CTLE [1]. However, analog front-ends (AFEs) are sensitive variations process, supply voltage and temperature. To combat this while accommodating links with loss exceeding 20dB, an AFE extensive programmability is combined efficient...
