摘要

蜂窝通信中的智能天线技术是增强通信网络潜力的一种好方法。在多径瑞利衰落信道中，智能天线存在的问题之一是无法准确检测到不同到达角度的到达信号。本文提出了一种新的智能天线信号处理方法，利用MUSIC方法对无线通信中信号的到达角进行估计。MUSIC是一种众所周知的高分辨率特征结构方法。本文还介绍了如何通过改变阵列天线的各种参数来提高估计过程的性能。在不同随机信号到达和不同阵元间距下进行了仿真。实验结果表明，该方法能较好地估计AOA。

Enhancing the performance of AOA estimation in wireless communication using the MUSIC algorithm

Smart antenna technology in cellular communication is an auspicious method to enhance the potential of communications networks. One of the problematic issues in smart antenna is the inaccurate detection of the arrival signal with different angles of arrival in multipath Rayleigh fading channel. In this paper, a new smart antenna signal processing method has been proposed for estimating the angle-of-arrival (AOA) of signals using the MUSIC method for wireless communication applications. MUSIC is a well-known high resolution eigen-structure method. This paper also describes how the performance of the estimation process can be enhanced by changing various parameters of the array antenna. The simulation has been conducted under different random signal arrivals and space between array elements. The achieved results show that the proposed method can estimate the AOA with higher efficiency.
