| 摘 要： | 简要阐述了阵列信号处理中广泛采用的MUSIC算法和MMUSIC算法的基本原理,然后理论分析了MUSIC和MMUSIC算法性能.仿真发现MMUSIC算法只能单独估计相干信号和非相干信号.针对这种情况,提出了一种修正MUSIC算法,该算法可以同时估计相干和非相干信号,计算机仿真结果证明该改进算法是有效的.

| Abstract: | Basic principles of MUSIC algorithm and MMUSIC algorithm, which are widely applied in array signal processing ,have been detailed introduced.Then the performance of MUSIC and MMUSIC algorithm are analyzed in this paper.Simulation results show that MMUSIC algorithm can only estimate coherent and non-coherent signal respectively. A modified MUSIC algorithm which can estimate coherent signal and non-coherent simultaneously is discussed.Computer simulation results show that the modified algorithm is effective. |
