Abstract :
A novel ESPRIT based decorrelating DOA estimation for CDMA frequency-selective fading channels 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 the proposed algorithm estimates the DOAs of multipath signals effectively and accurately.
