摘　　要：A novel decorrelating DOA estimation algorithm of multipath signals for CDMA frequency selective fading channels based only on the principal eigenvector of its corresponding covariance matrix is proposed. The proposed algorithm has the advantages that the DOAs of the multipath signals can be estimated independently and all the other resolved multipath signal interference is eliminated. Simulation results show that this algorithm estimates the DOAs of multipath signals efficiently and accurately. 提出了一种新的只基于所对应协方差矩阵主特征矢量的同步CDMA频率选择性衰落信道的多径信号的解相关DOA或AOA估计算法 .所提出的算法具有能消除其他多径信号干扰独立地估计期望信号到达角的优点 .仿真结果表明该算法可高效。
