摘要
针对基本MUSIC算法是在信源正确估计的条件下才能应用的情况,论述了一种在欠估计的情形下改进的MUSIC算法,并将此改进算法成功地用于相干信号中,扩展了改进算法的适用范围。仿真结果证明了这种扩展的有效性。
MUSIC algorithm has good performance only under the correct-estimation of source number,in order to expand the applicational area of MUSIC. A new modified MUSIC algorithm which has good performance for coherent signal is discussed. Simulation results show the effectiveness of proposed algorithm.
