摘要
用隐滤波器隐马尔柯尔夫模型从相似功率谱噪声中检测脑电信号，运用似然比检验的方法对混有噪声的脑电信号进行检测．实践表明，该方法检测效果较好。
The detection of EEG signal buried in noise with the similar power spectrum is investiga ted. By using the hidden filter hidden Markov model (HFHMM),a likelihood radio test is adopted to detect combined signal and noise,and good experimental ROC for a variety of SNR down to -18 dB is obtained.
