GPS C/A码捕获 用的是fft频域的搜索 有C/A码产生和C/A码数字化子程序，模拟卫星信号的捕获算法和过程，未考虑多普勒频移-GPS C/A code acquisition in frequency domain using the fft search with C/A code generation and C/A code number of subroutines, analog satellite signal acquisition method and process, w

离散小波变换是指在特定子集上采取缩放和平移的小波变换，是一种兼具时域和频域多分辨率能力的信号分析工具。此变换运用可以缩放平移的小波代替固定的窗进行计算分析，主要应用于信号编码和数据压缩。-Discrete wavelet transform refers to the specific subset take scaling and translation on the wavelet transform, is a kind of multi-resolution ability both t

对频域稀疏的简单信号进行仿真，滤波器系数服从贝努利分布-The frequency domain signal simulation sparse simple filter coefficients Bernoulli distribution

本课题研究设计了一个图形用户界面（Graphical User Interface，简称 GUI，又称图形用户接口），用以调用显示出心音信号的时域波形、频域波形、能量分布、心率以及一些特征信息。-This paper has designed a graphical user interface (Graphical User Interface, referred to as GUI, also known as the graphical user interface),which used
