Abstract :
The MUSIC algorithm is well known for its high resolution capability and various aspects of its statistical performance have been investigated. but performance will decrease to coherent signal and colored noise. In this paper, Using Four-order Cumulants and Modified Music algorithm for DOA has a good performance. The algorithm of coherent signal based on Fourth-order Cumulants has good statistical performance in Gaussian colored noise, and is effective in implementing high-resolution DOA estimation of coherent signal.
