Abstract :
An adaptive array antenna is proposed based on the radial basis function (RBF) network as a multiuser detector for a WCDMA system. The proposed system calculates the optimal combining weight coefficients using sample matrix inversion with a common correlation matrix algorithm and obtains the channel response vector using the RBF output signal
