A 2-D DOA Estimation for CDMA Signal

Based on three orthogonal linear arrays within DS-CDMA system,this paper proposes a method to estimate 2D-DOA.This method utilizes one of the three linear arrays to pair the 1-D DOA which is estimated by the other two linear arrays respectively.Because of the sufficient use of the characteristics of CDMA and 2-D processing,it can polish MUSIC algorithm and improve the capability of DOA estimation.The simulation results show the feasibility and effectiveness of the method.
