摘要

本文提出了利用广义负熵盲检测机理对混沌超宽带系统的进行非相干盲检测的研究方法, 在传输信道状态未知的情况下即可检测出混沌脉冲信号. 该方法能够克服用于超宽带无线电通信的直接混沌通信方案存在的实际应用问题, 能够有效解决未知复杂多径信道问题. 通过仿真结果分析表明, 采用非相干盲检测方法的直接混沌通信超宽带方案, 不需要信道状态信息, 具有很好的分离检测效果. 为未知非理想信道下, 非相干盲检测的混沌超宽带系统提出了新思路.

Abstract

A non-coherent blind detection method based on the generalized negative entropy mechanism for chaotic ultra-wideband system is proposed in this paper. In the case without knowing the transmission channel information, the chaotic impulse signals can be detected. The proposed method can overcome the practical application problem existing in the direct chaotic communication (DCC) scheme for impulse radio ultra-wideband (IR-UWB) communication system. Also, this method can overcome the complicated and unknown multipath channel effect. Analysis of simulation results show that the proposed approach has a good separating and detection performance in the case without the channel information. A new way for the noncoherent blind detection of chaotic UWB system under non-ideal unknown channel is established.
