论文摘要
我们提出了一个多元对数正态分布，以接收到宽带无线电通道的宽带无线电通道的共同模型，平均延迟（RMS）延迟传播，称为标准化的时间矩。使用从五个不同的测量活动（四个室内和一个室外场景）收集的实验数据验证该模型。我们观察到接收的功率，平均延迟和RMS延迟扩散是相关的随机变量，因此应共同模拟。与文献中考虑的独立模型不同，联合模型能够捕获基础过程的结构。发现多元对数正态分布的建议模型非常适合大量宽带数据集。
We propose a multivariate log-normal distribution to jointly model received power, mean delay, and root mean square (rms) delay spread of wideband radio channels, referred to as the standardized temporal moments. The model is validated using experimental data collected from five different measurement campaigns (four indoor and one outdoor scenario). We observe that the received power, mean delay and rms delay spread are correlated random variables and, therefore, should be simulated jointly. Joint models are able to capture the structure of the underlying process, unlike the independent models considered in the literature. The proposed model of the multivariate log-normal distribution is found to be a good fit for a large number of wideband data-sets.
