现代信息检测处理的信号具有微弱、非线性、多输入多输出、实时性高等特点，迫切需要高效的信号检测和处理方法。本课程将结合发表在国际期刊上的论文，介绍相关和谱估计、最优滤波、独立分量分析、小波变换与Hilbert-Huang变换等多种新型信号处理方法在现代信息检测中的应用。

There are some prominent features in the modern measurement, such as the low-level and nonlinear signal, multi-inputs multi-outputs, and high real-time requirement. It is of importance to detect and process the signal efficiently. Combined with published paper in the international journal, this course introduces the correlation and spectrum estimation, optimal filtering,indenpedent compondent analysis, wavelet transform, Hilbert-Huang Transform, and so forth, as well as the application in the modern measurement.
