摘要：
An efficient implementation of DOA estimation is proposed for DS-CDMA systems with smart antennas. We suggest that the received signal is first decoded to enhance its SNR and reduce its complexity, then a rough estimation is done to simplify ANN structure before data is processed by BP ANN network. Simulation results show this method is more precise, stable and can endure lower SNR than many other algorithms.
