摘要

提出了一种基于分形理论的麻醉监测诱发脑电信号识别方法.首先给出了麻醉监测中潜伏期听觉诱发脑电信号的数学模型

产生与实际信号相符的模拟脑电信号

然后对脑电信号进行小波降噪

提取降噪后脑电信号的关联维数

最后通过关联维数的大小识别麻醉状态下中潜伏期听觉诱发脑电信号的类型.实验仿真结果表明:提出的识别方法具有较高的识别率.

Abstract

A identification method based on fractal theory was proposed.First

the simulation model of mid-latency auditory evoked potentials (MLAEP) signal is gave out and the simulation MLAEP signal which is according with reality during anesthesia monitoring is built up.Then

the noise in evoked potential signal is denoised through the wavelet transform method and the correlation dimensions are computed.Finally

according to the correlation dimension

the signal type is identified for evoked potential signal during anesthesia monitoring.The experimental simulation results show that the proposed method has higher identification rate for MLAEP during anesthesia states.
