摘要

A novel phase acquisition method of code division multiple access (CDMA) address code is proposed in this paper. Based on the combination of chaotic nonlinear maps and backpropagation neural networks, this new approach can be applied to realize the phase acquisition of a CDMA address code, which plays an important role in wireless mobile communications. Both the theoretical analysis and computer simulation results show that it can increase the detection probability of the received signals compared with the conventional series acquisition method, which can improve the performance of the CDMA receiving system significantly.
