摘要 提出一种基于ARake(All Rake)接收机思想的UWB(Ultra-Wide Band)信道模型改造方法。该方法根据UWB系统脉冲成形方案的具体要求,将IEEE802.15.3a标准信道模型改造为具有特定中心频率和多径分辨率的抽头延时线模型。改造后的信道模型为系统设计提供了指导信息,并简化了系统性能分析和仿真。针对典型UWB成形脉冲给出改造实例,对改造后信道模型的统计特征进行了分析。 A modification method, based on ARake receiver theory, for UWB channel model is proposed. In accordance with the UWB pulse shaping scheme, it can modify the IEEE802.15.3a channel model into a tapped-delay-line channel model with specific center frequency and multipath resolution. The modified channel model provides design reference and simplifies the system analysis and simulation. As an example, the modification for a typical UWB pulse has been done, and the statistic characters of the modified channel model have been analyzed.
