Adaptive Chaotic Neural Network and Implementation of CDMA Multiuser Detector

An improved adaptive chaotic neural network algorithm was proposed and applied to the CDMA multiuser detection technique. During the optimal searching process, this algorithm adjusts network parameters according to the change of the energy function of transient chaotic neural network. So it can control the energy function to produce favorable influence on the dynamics of neural network adaptively. The simulation results show that the multiuser detector based on improved adaptive chaotic neural network can approach the performance of the optimum CDMA multiuser detector effectively.
