Abstract

As one of the technologies used to overcome multipath fading in land mobile communications, adaptive array antennas and adaptive equalizers have been investigated. To put adaptive array antennas to practical use, the multipath signal propagation characteristics, such as the time delay and arrival direction, must be clarified. This can be accomplished via the antenna design and by developing an adaptive algorithm. The author has already proposed methods for measuring complex delay profiles with a virtual planar array. This involved scanning a linear array antenna and estimating the time delays and arrival directions of multipath signals by a two-dimensional discrete Fourier transform. This time, the author applied MUSIC algorithm to the virtual planar array to precisely estimate the arrival directions of multipath signals. In this paper, the performance and features of the MUSIC algorithm in estimating the arrival directions of multipath signals via computer simulation are clarified.

基于平面阵列的MUSIC算法估计到达方向

自适应阵列天线和自适应均衡器是陆地移动通信中克服多径衰落的技术之一。为了使自适应阵列天线实际应用，必须明确多径信号的传播特性，如时延和到达方向。这可以通过天线设计和自适应算法来实现。作者已经提出了用虚拟平面阵列测量复杂延迟分布的方法。这涉及到扫描线性阵列天线，并通过二维离散傅里叶变换估计多径信号的时间延迟和到达方向。本文将MUSIC算法应用于虚拟平面阵列，对多径信号的到达方向进行精确估计。本文通过计算机仿真，阐述了MUSIC算法在估计多径信号到达方向方面的性能和特点。
