| 摘 要： | 在室内通信环境中，超宽带信号具有多径成簇到达的特性。利用此特性，文中提出了两种基于最大似然准则的分簇信道估计算法，仿真结果表明，与传统的最大似然信道估计算法相比，丈中的两种算法大大降低了系统的复杂度和误码率。

| Abstract: | For indoor communications, UWB channels exhibit a clustering of path arrivals. By taking good use of this characteristic, this paper presents two ML-based clustered channel estimation algorithms. The simulation result shows that, compared with the conventional ML channel estimation strategy, these two algorithm are more effective in BER degradation. |
