摘要：
A blind beamforming algorithm based on OBE algorithm is presented. First, the signal model of adaptive algorithm is constructed according to the principle of smart antennas. Second, the structure of the algorithm is discussed, and the algorithm is based on despread respread judging direction. The optimal weight is iteratively estimated on the mean square error (MSE) criterion. Third, the principle of OBE is studied, and the iterative equation of adaptive beamforming is constructed. Last, the performance of the algorithm is simulated. It is shown from simulation results that the algorithm satisfies the requirements of adaptive beamforming, and has better convergence and output performances than LS-DRMTA.
