fetal ecg detection using matlab

在现代信号处理中对信号进行的多种加窗操作程序，如hamming窗，hanning窗(In modern signal processing of signals, plus multi-window operation, such as the Hamming window, hanning window)

一种基于均匀圆阵的传播算子高分辨算法，能快速准确进行360度的DOA估计(A method based on uniform circular array propagator high resolution algorithm, can be fast and accurate to360 degrees DOA estimation )

五点三次法实现振动信号趋势项的消除， 1、 计算出数据的均值、均方值、方差 ； 2、 用matlab编制五点三次法消趋势项程序。 3、 在同一坐标下绘出消趋势项前后时域信号，并分析比较。 绘出消趋势项前后信号的自相关函数。( Five points three times a method to achieve the elimination of the trend of the vibration signal, 1, to calculate the mean of the data, the mean square value, variance 2, the preparation of the five points three times France extinction trend procedure using matlab. 3, plotted in the same coordinate consumer trends before and after the time-domain signal, analyzed and compared. Draw to eliminate the trend before and after the signal autocorrelation function. )
