毫米波(MmWave)通信是一种很有前途的解决方案,可以解决当前由快速增长的移动数据需求造成的全球带宽短缺问题。虽然毫米波传输的信道建模和传播特性已经相当清楚,但瞬时信道特性,包括人的手如何阻止手机中的天线,需要进行新的、详细的研究。此外,毫米波定向波束形成面临的干扰的影响和性质还有待深入研究。该提案涉及瞬时信道特性和干扰建模的关键方面将直接有助于实现毫米波通信,这不仅针对传统的固定基础设施蜂窝服务,而且针对新兴的、更普遍的新服务模式,包括在公共汽车、火车和汽车上的未经许可和移动使用,以及点对点通信。首先,该提案描述了毫米波频道中的瞬时物理效应,例如拿着手机时由于人的手、头和身体放置而导致的衰落。这一特征将通过使用定向天线的广泛测量和使用有限状态马尔可夫模型的新的建模方法来进行。这些暂态信道模型随后将被集成到基于测量的开源信道仿真平台NYUSIM中,该平台可在多种实际设置下生成逼真的毫米波信道脉冲响应。其次,该方案提供了采用波束成形的毫米波蜂窝系统中干扰分布的分析模型,包括每个接收天线单元的干扰功率和不同天线单元之间的干扰相关性以及干扰信号和预期信号之间的相关性的显式概率密度函数。这些分布是参数化的和重尾的,以便捕捉由于强阴影和在密集环境的典型毫米波应用中NLOS传播的高概率而导致的毫米波信号的巨大波动。干扰模型通过与使用随机几何对用户和基站的位置建模并使用NUYSIM在所有节点之间生成真实的毫米波信道的系统仿真进行比较来验证。这项拟议的研究整合了测量、建模、理论和分析,以促进对毫米波通信的基本理解,为设计和评估毫米波通信系统提供了一种手段。该奖项反映了NSF的法定使命,并通过使用基金会的智力优势和更广泛的影响审查标准进行评估,被认为值得支持。
英文摘要
Millimeter-wave (mmWave) communication is a promising solution to the current global shortage of bandwidth created by the rapidly growing demand for mobile data. While channel modeling and propagation characteristics for mmWave transmissions are fairly well understood, transient channel characteristics including how the hand of a human blocks antennas in a handset requires new, detailed research. Further, the impact and nature of interference in the face of mmWave directional beamforming are yet to be well explored. The key aspects of this proposal dealing with transient channel characterization and interference modeling will directly contribute to the realization of mmWave communications, which is envisioned not only for traditional fixed infrastructure cellular services but also for emerging, more prevalent, new service modes including unlicensed/licensed and mobile usage such as on buses, trains and cars, and peer to peer communications.This proposal advances understanding in several fundamental aspects of mmWave communications. First, the proposal characterizes transient physical effects in mmWave channels such as fading due to human hand, head and body placement when holding phones. This characterization will be carried out with extensive measurements using directional antennas and novel modeling methodology employing finite-state Markov models. These transient channel models will then be integrated into the open-source measurement-based channel simulation platform NYUSIM, which generates realistic mmWave channel impulse responses under a wide range of practical settings. Second, the proposal provides analytical models of the interference distribution in a mmWave cellular system employing beamforming, including explicit probability density functions for the interference power at each receiving antenna element and interference correlation between different antenna elements as well as correlation between interference signals and intended signals. These distributions are parameterized and heavy-tailed in order to capture the large fluctuation in mmWave signals due to strong shadowing and a high probability of NLOS propagation in typical mmWave applications of dense environments. The interference models are verified by comparing with a system simulation using stochastic geometry to model locations of users and base stations and using NUYSIM to generate realistic mmWave channels among all nodes. The proposed research integrates measurement, modeling, theory, and analysis to advance fundamental understanding of mmWave communications, providing a means towards designing and evaluating mmWave communication systems.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.
