论文摘要
在建筑物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无线绩效（BWP）评估理论，重点是通道延迟扩展（DS）。本文的新颖贡献在于以下方面。 1）我们定义了一个名为DS Gain的新指标，该指标是评估设计中建筑物的频道DS性能的第一个指标。 2）我们提出了一个分析模型，以快速准确地计算度量。 3）在典型的室内场景下，通过蒙特卡洛模拟验证了所提出的方案。数值结果表明，建筑物设计对根平方（RMS）ds有明显的影响。将来，建筑师需要设计建筑物的DS收益。否则，由于大量DS增益，其室内网络将遭受严重的信号符号间干扰（ISI）。
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.
