Abstract
In this paper, an effective DOA estimation algorithm, element-wise division operation, is presented for DS-CDMA system under multi-user environment. Because the algorithm requires neither complex eigenvalue decomposition operations nor source number estimation, the algorithm can be realized timely utilizing DSP device TMS320, and the circuit structure and flow chart is presented.
