We present a new design of a 60 GHz mesh networks based on IEEE 802.11ad. By using an edge/vertex-coloring algorithm to carefully allocate the channels in the mesh network, the co-channel interference of the mesh network, particularly intra-node interference, can be significantly reduced. In our prototype, we found that with 90° angle separation, there is negligible intra-node interference and rate loss. Furthermore, our indoor demonstrations with multi-hop transmissions showed that end-to-end throughput as high as 1.7 Gbps can be achieved.
提出了一种基于IEEE 802.11ad的60ghz网状网络的新设计。利用边缘/顶点着色算法对mesh网络中的信道进行精细分配,可以显著降低mesh网络的同信道干扰,特别是节点内干扰。在我们的原型中,我们发现在90°角分离的情况下,节点内干扰和速率损失可以忽略不计。此外,我们对多跳传输的室内演示表明,端到端吞吐量可以达到1.7 Gbps。

An analytical approach introduced in 1960 by Russian scientist Tereshin [1]–[2], for decoupling two antennas using an impedance surface is presented. An impedance surface expression is practically realized using corrugations of varied depth onto a cylindrical RF repeater platform and fabricated using 3D-printing. The coupling is measured and obtained results show that the impedance structure decreases the coupling by 11 dB over a wide range in KiKa-band.

In this paper, we propose to employ the Markov jump linear system to model the characteristics of millimeter wave (mmWave) signals, such as signal strength and angle-of-arrival (AoA), for mobile users. We integrate the spatial correlation between line-of-sight (LoS) and none-line-of-sight (NLoS) beams to the stochastic framework for better modeling mmWave. To handle the channel dynamics in mmWave communications, we derive a Markov gain-state channel model based on channel measurements in an indoor environment from our field measurement. The proposed stochastic model is used to estimate the transition probability of each channel. Then it is integrated into the Markov jump linear system framework to construct the linear estimator for channel variables, such as AoA and channel gain. The simulation result demonstrates the outperformance of the proposed framework against the previous Kalman-filtering-based tracking algorithm.
在本文中,我们建议使用马尔可夫跳变线性系统来模拟毫米波(mmWave)信号的特性,如信号强度和到达角(AoA),用于移动用户。我们将视线(LoS)和非视线(NLoS)波束之间的空间相关性整合到随机框架中,以便更好地建模毫米波。为了处理毫米波通信中的信道动态,我们从现场测量中导出了基于室内环境中信道测量的马尔可夫增益状态信道模型。提出的随机模型用于估计每个信道的转移概率。然后将其集成到马尔可夫跳变线性系统框架中,构造信道方差和信道增益等信道变量的线性估计器。仿真结果表明,该框架相对于先前基于卡尔曼滤波的跟踪算法具有优异的性能。

This work presents a modular wideband transmitter channelizer for high data rate communication applications, manufactured in a 130 nm SiGe:C BiCMOS technology with fT / fmax= 300/500 GHz. Three independent I/Q baseband signals are upconverted to different intermediate frequencies and then bonded in current domain. A local oscillator leakage cancellation functionality is implemented on chip within the input stage to enhance the dynamic range. Single ended inputs were utilized in order to reduce the pin count, for a more practical realization and higher potential toward future system scaling. The transmitter channelizer achieves an output 3-dB bandwidth of 15 GHz. LO rejection of 74 dBc at the center frequency was measured after calibration. It dissipates 355 m Wand occupies 1.5 mm2. With these specifications the presented circuitry suits well as a practical solution for wideband channelization for high data rate transmission scenario's, such as THz and sub-THz communications applications, with a potential scaling-up to higher number of channels.
这项工作提出了一种用于高数据速率通信应用的模块化宽带发射机信道器,采用130 nm SiGe:C BiCMOS技术制造,fT / fmax= 300/500 GHz。将三个独立的I/Q基带信号上转换为不同的中频,然后在电流域中进行键合。芯片在输入级内实现了本振漏损消除功能,提高了动态范围。使用单端输入是为了减少引脚数,以实现更实际的实现,并为未来的系统扩展提供更高的潜力。发射机信道转换器输出3db带宽为15ghz。校正后测量了中心频率处74 dBc的LO抑制。它的耗散为355 m,魔杖占地1.5 mm2。有了这些规范,所提出的电路很适合作为高数据速率传输场景的宽带信道化的实用解决方案,例如太赫兹和次太赫兹通信应用,具有潜在的扩展到更高数量的信道。

We describe a set of compact millimeter-wave frequency converters for wideband digital signals. Frequency upconverters and downconverters have been developed for frequencies from WR-28 (26–40 GHz) to WR-2.2 (325–500 GHz). Bandpass filters with passband return loss> 20dB and stopband rejection> 50dB within 1 GHz from band edges were developed for use with these upconverters. Preliminary WR-12 link tests are shown.

In this paper, a novel millimetre wave (mm-Wave) flat lens antenna system and its feed network co-designed on a mainstream print circuit board (PCB) technology is presented. It is capable of achieve 3600 coverage scan in Azimuth plane with> 14 dBi measured peak gain and the measured return loss is < 10 dB. Steering in the Elevation plane is designed to be 150upwards; this is controlled by the metal flanges opening angles as they are soldered on both side of the lens. This lens antenna system can be a great candidate for 5G access point operates at mm-Wave. The same technique could be also applied in smaller devices such as cellular phone or tablets.

A planar dually-polarized six-port junction is presented for polarimetry remote sensing. The novelty of the proposed polarization-inclusive remote sensing concept lies in the way the orthogonal polarizations are measured and compared to the reference signal. The core of the proposed system is the dually-polarized individual components such as the dually polarized waveguides, hybrid couplers and phase shifters. The signal flow in the proposed system is explained in details. An example for the analytical procedure to design millimeter wave dually-polarized phase shifter is explained in details.

Measurements of High-Intensity Radio-Frequency Electric Fields with Rydberg Vapors 用里德伯蒸汽测量高强度射频电场

Measurements of radio-frequency (RF) electric fields in the MHz-to sub-THz range using EIT spectroscopy of Rydberg states in atomic vapors have garnered significant interest in recent years. Here we describe recent work extending the approach to measurements of coherent high-intensity RF electric fields above 1 kV/m and continuous-frequency RF measurement capability. The spectra are modeled using a non-perturbative Floquet model that accounts for higher-order interactions and state mixing. The spectroscopic data also reveal nonlinear amplifier behavior and noise.

Worst Month Tropospheric Attenuation Variability Analysis: ITU Model vs. Rain Gauge Data for Air-Satellite Links 最坏月份对流层衰减变异性分析:国际电联模型与空中-卫星链路雨量计数据

An important unmanned aircraft system (UAS) application area is in rescue functions in remote areas, where ground station control may not be applicable. In such settings, an air-satellite (AS) communication link may be required. For transmissions in the millimeter wave (mmWave) frequency bands, rain attenuation can be a dominant fading component in the AS link, especially in so-called “worst month” conditions. Several models have been established by the International Telecommunications Union (ITV) to quantify rain attenuation. However, since the models are for global use, results are not always sufficiently accurate in local areas. Hence the use of local precipitation data can improve rain attenuation estimation accuracy. In this paper, we investigate attenuations in the AS channel in two frequency bands (30 and 45 GHz) for Columbia, SC. We use local rain gauge data from the National Oceanic and Atmospheric Administration (NOAA), along with the regional ITV data, as inputs to the ITV tropospheric time series attenuation model. Statistical results for attenuation distributions and time series are analyzed for the worst month. We show that use of local measured rain gauge data can yield rain fades significantly larger than those predicted by the regional ITV data-on the order of 20 dB larger, for probabilities (~ fractions of time) ranging from 0.001 to 0.04.
无人机系统的一个重要应用领域是偏远地区的救援功能,在这些地区,地面站控制可能不适用。在这种情况下,可能需要空中卫星(AS)通信链路。对于毫米波(mmWave)频段的传输,雨水衰减可能是AS链路中主要的衰落成分,特别是在所谓的“最差月份”条件下。国际电信联盟(ITV)已经建立了几个模型来量化雨水衰减。然而,由于这些模型是供全球使用的,结果在局部地区并不总是足够准确。因此,利用局地降水资料可以提高雨衰减估计的精度。在本文中,我们研究了哥伦比亚州AS通道在两个频段(30和45 GHz)的衰减。我们使用来自美国国家海洋和大气管理局(NOAA)的当地雨量计数据以及区域ITV数据作为ITV对流层时间序列衰减模型的输入。对衰减分布和时间序列的统计结果进行了最坏月份的分析。我们表明,使用当地测量的雨量计数据可以产生比区域ITV数据预测的雨渐大得多的雨渐,在概率(~时间分数)范围从0.001到0.04的数量级上大20 dB。

A suit of enabling passive components covering entire V-and W-bands, i.e. 45–110 GHz, is built for the support of future RF repeater research and development efforts. Concerns such as loss, power handling, dispersion, and singlemode bandwidth are considered to design a custom double-ridge waveguide and components including antennas, bends, twists, dividers, hybrids, couplers, filters, and decoupling surfaces, just to name a few. Results show that the developed technology can pave the way for efficient, low-cost integrated wideband or multiband millimeter wave systems.
为支持未来RF中继器的研究和开发工作,构建了一套覆盖整个v和w频段(即45-110 GHz)的使能无源组件。考虑损耗、功率处理、色散和单模带宽等问题,设计定制双脊波导和组件,包括天线、弯曲、扭曲、分频器、混合动力、耦合器、滤波器和去耦表面,仅举几例。结果表明,所开发的技术为高效、低成本的集成宽带或多波段毫米波系统铺平了道路。
