Applications of Stochastic Bridge Methods for UWB Wireless Channel

  • 摘要: 該文使用隨機橋方法研究超寬帶室內多徑信道。首先介紹隨機橋理論,分析UWB室內多徑信道的物理基礎;然后對UWB脈沖信號失真問題和脈沖信號的相位問題進行深入分析。把UWB信號在信道中發(fā)生的傳播損耗和與散射體發(fā)生碰撞產生的損耗分開,假設UWB多徑信號的傳播路徑為布朗橋過程,同時采用雙值相位假設,得到布朗橋模型信道沖激響應。對有金屬網格玻璃門反射的走廊環(huán)境進行仿真,得到的UWB信道功率時延分布與公布的UWB信道測量結果一致。
