ECG--QRS
以软件为主的方法实现QRS波的检测滤波之后的信号一般经过一些
变换以提高QRS波的份量，进而采用一系列阈值进行判别，这些阈值有固定
阈值法，也有可变阈值法。前者由于可能的干扰或高P、高T波的存在，若
其滤波后超过其阈值便会产生假阳性(FP，falsepositive)结果；另外，当心
律失常或QRS波幅度变小，阈值设置过高，会导致漏检产生假阴性(FN，
falsenegative)结果。由于固定阈值的这些缺点，有研究者提出了用可变阈
值检测，以提高检测的精确率，所采用的可变阈值包括幅度阈值、斜率阈值
和时间间隔阈值等。(Give priority to with software method for detecting QRS wave signal after some commonly after filtering
Amount of transformation in order to improve the QRS wave, then using a series of threshold to distinguish, the threshold value is fixed
Threshold value method and variable threshold value method. The former due to the possible interference or the existence of the high P and T waves, if
More than the threshold value is created after the filtering false positives (FP, falsepositive results In addition, be careful
Law of disorder or QRS wave amplitude decreases, threshold is set too high, can lead to leak to produce false negatives (FN,
Falsenegative) results. Due to these disadvantages of fixed threshold, some researchers have proposed using variable threshold
Value detection, in order to improve the precision of detection rate, adopted by the variable threshold including amplitude threshold, the slope threshold
And the time interval threshold, etc.)

QPSK
Direct sequence spread spectrum (DSSS) communication systems has been widely
used in these years for its advantage of wide spectrum, low working Signal-to-Noise
ratio (SNR), anti-interference, anti-multipath effect and capability of LPI and LPD.
They are increasingly replacing conventional communication forms and obtaining
extensively applications in modern military and commercial communication systems,
for example, CDMA communication system, GPS , measuring and control system,
satellite chain, identification of friend or foe and etc. Therefore, corresponding DSSS
electronic counter technique becomes a big problem to solve in electronic warfare
domain. DSSS electronic counter technique including blind detection, blind parameter
estimation and spreading sequences estimation. For the issue of DSSS electronic
counter technique of DSSS/QPSK signal damaged by strong additive white Gaussian
noise (AWGN), the main research content in this dissertation as follow.
