建筑物布局的无线信道延迟扩展性能评估
Wireless Channel Delay Spread Performance Evaluation of a Building Layout
摘要：
在建筑设计过程中评估建筑物的无线性能是无线通信和建筑设计的新范式。本文提出了最早的建筑物无线性能（BWP）的评估理论，侧重于信道延迟扩展（DS）。本文的创新之处在于以下几个方面。1)我们定义了一个新的度量称为DS增益，这是第一个度量评估的信道DS性能的建筑物设计。2)我们提出了一个分析模型来快速准确地计算度量。3)在典型的室内场景下，通过Monte-Carlo仿真验证了所提出的方案。数值结果表明，建筑物的设计有明显的影响的均方根（RMS）DS。在未来，建筑师需要设计一个建筑物考虑其DS增益仔细考虑。否则，室内网络将遭受严重的信号符号间干扰（ISI）由于过大的DS增益。
英文摘要：
Evaluating a building's wireless performance during the building design process is a new paradigm for wireless communications and building design. This paper proposes the earliest building wireless performance (BWP) evaluation theory focusing on the channel delay spread (DS). The novel contributions of this paper lie in the following aspects. 1) We define a new metric called DS gain, which is the first metric for evaluating the channel DS performance of a building under design. 2) We propose an analytical model to compute the metric quickly and accurately. 3) The proposed scheme is validated via Monte-Carlo simulations under typical indoor scenarios. Numerical results reveal that building design has a clear impact on the root mean square (RMS) DS. In the future, architects need to design a building taking its DS gain into account carefully. Otherwise, indoor networks in it will suffer from severe signal inter-symbol interference (ISI) due to an over large DS gain.
