与一般的串行捕捉法相比

该方法可使CDMA地址码的检测概率得到提高

平均捕捉时间得到减小

从而使移动通信系统的整体性能得到有效的改善.

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.
