Abstract

Abstract

Having compared two classic smart antenna DOA (Direction of Arrival, DOA) estimation algorithmdelay-sum algorithm, multiple signal classification (MUSIC) algorithm, smart antennas direction of arrival estimation based on wavelet transformer (SADOAWT) algorithm has been proposed. Taking into account the computational complexity and convergence rate, the algorithm converts signal into multiple scales domain, while different frequency domain would use different algorithms. Simulation results show that the computational complexity of new algorithm is low. SADOAWT overcomes the disadvantages of delay-sum algorithm which has low resolution and many sidelobes, it also avoids the problem that resolution of MUSIC algorithm gets reduced while correlated signal coming.
