摘要：
The accurate estimation of the transmission parameters and the direction of arrival(DOA) are the keys in the array antenna code-division multiple access(CDMA) system. This paper introduces the artificial neural network to estimate DOA and adopts a blind estimation algorithm based on the cyclostationarity features of the received signal to compute the random time-delay. The pilot sequence is unnecessary for the blind parameter estimation algorithm, so the transmission efficiency can be improved. Moreover, the performance of proposed algorithm is simulated by using of beamforming.
