对 EEG脑电信号的有效处理和分析，可以判断不同的脑机能状态，在神经生理科学研究和临床诊断中有着广泛应用。考虑到 EEG脑电信号中每个单独的生物信号时间上的相关性和不同信道生物信号之间的信道间相关性，基于离散余弦变换基对 EEG脑电信号进行稀疏化，并利用基于块稀疏贝叶斯的压缩传感技术对其进行仿真重构。大量实验结果表明，重构的 EEG脑电信号与原信号具有极大的相似保真度，能够用于医学上的进一步处理。

With careful analyses and processing, some characteristic parameters can be extracted for identifying different cerebral function states. EEG has been used in neurophysiology researches and clinical disease diagnosis widely. We design sparse of EEG signal based on discrete cosine terminal and use compressed sensing technology based on block sparse Bayesian to reconstruct the signal, concerned both temporal correlation in each individual biosignal and inter-channel correlation among biosignals from different channels. A large number of experimental results show that, there is greatly similar fidelity between the reconstructed EEG signal and the original signal, and it can be used for further processing of the medical.
