随着移动通信技术的飞速发展，智能天线技术研究的不断深入，来波方向

(DOA)

估计技术逐渐成为研究的热点之一，

而

MUSIC

算法是智能天线技术的典型

算法。本文在对

MUSIC

算法进行分析的基础上，设计了

MUSIC

算法的仿真程序，

对不同情况下该算法的性能进行了仿真分析。

仿真结果表明该算法在不同阵列结

构、信号入射角度时具有不同的性能。(With the rapid development of mobile communication technology, the research of smart antenna technology is deepening, direction of arrival (DOA) estimation technique becomes a research hotspot, and the music algorithm is a typical algorithm of smart antenna technology. Based on analyzing the music algorithm on the design of the music algorithm simulation program, the performance of the the algorithm under different conditions are simulated and analyzed. Simulation results show that the algorithm in different array structures with different properties)
