| Abstract: | An improved neural network detection method based on Logistic map and BP (back propagation) network is proposed.It can be applied to phase acquisition of CDMA address code.The results of analysis and simulation both show that it can increase the detection probability and reduce the average acquisition time compared with conventional series phase acquisition method,and the performance of the whole mobile communication system can be improved effectively. |
