The problem of direction of arrival (DOA) estimation of mobile users using linear antenna arrays is addressed, To reduce the computational complexity of superresolution algorithms, e.g. multiple signal classification (MUSIC), the DOA problem is approached as a mapping which can be modeled using a suitable artificial neural network trained with input output pairs, This paper discusses the application of a three-layer radial-basis function neural network (RBFNN), which can learn multiple source-direction findings of a six-element array, The network weights are modified using the normalized cumulative delta rule, The performance of this network is compared to that of the MUSIC algorithm for both uncorrelated and correlated signals, It Is also shown that the RBFNN substantially reduced the CPU time for the DOA estimation computations.
