我们提出了一种通用的超宽带(UWB)多径无线信道模型，该模型是为链路级模拟而设计的，适用于室内环境，例如WPAN应用。它覆盖FCC频段[FCC，2002年2月]，并能够产生空间可变的脉冲响应(IR)和传递函数。该模型是一种混合型模型，它结合了一种统计方法来模拟密集多径，以及一种简单的准确定性方法来模拟强烈的个体回波。这些回波对于获得逼真的空间(多普勒)行为很重要。该模型的结构便于在UWB MIMO分析中的应用。对于几种情况(例如，局内和局间传输)，给出了从测量数据导出的特定于站点的参数简档。
We present a generic ultra-wideband (UWB) multipath radio channel model that has been designed for link-level simulations and is suited for indoor environments, e.g. for WPAN applications. It covers the FCC frequency band [FCC, Feb. 2002] and is capable of producing space-variant impulse responses (IR) and transfer functions. The model is of a hybrid type and combines a statistical approach to model dense multipath and a simple quasi-deterministic method to model strong individual echoes. These echoes are important to obtain a realistic spatial (Doppler) behavior. The architecture of the model facilitates the application to UWB MIMO analyses. For a few scenarios (e.g., intra-office and inter-office transmission), site-specific parameter profiles are given that have been derived from measured data.
