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。
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.
