| 摘 要： | 超宽带(UWB-Ultra Wide Bandwidth)通信技术是无线通信中的一个非常有发展前途的技术.基于频域模型的UWB到达角估计方法只能解决非相干源问题,因此提出了一种改进的估计方法.该方法通过构造聚焦矩阵来估计相干源问题.仿真结果表明,该方法有效易行.

| Abstract: | Ultra wideband (UWB) technology is a very attractive technology for wireless communications. An estimation method of direction of arrival (DOA) for UWB based on frequency modeling cannot deal with coherent sources. Thus,a modified method is presented which construct a focusing matrix to estimate coherent signals. Simulation result shows that the algorithm is effective. |
