In this letter, we propose a simple and useful approach based on artificial neural networks (ANNs) to help the determination process of the despreading sequences weighted by exponential chip weighting waveforms in a low processing gain direct sequence-code division multiple access (DS-CDMA) system. Numerical results show that the parameter values of the exponential chip weighting waveforms produced by the proposed network are nearly optimal and satisfactory in viewpoint of the achieved bit error rate (BER) performance.
