对雷达多脉冲回波进行匹配滤波处理后，再进行相参积累，提高检测信噪比(Coherent matched filter radar multi-pulse echo, to improve the detection signal to noise ratio)

基于阈值分割心音信号，阈值可根据信号调整，程序给出心音分割的起止位置。(Threshold-based segmentation of heart sound signals, the threshold can be adjusted according to the signal, the program gives the starting and ending positions of heart sounds segmentation.)

说明：  这个连续信号的表现图像，作为matlab领域中最常见的内容，可以掌握(The performance of the continuous signal image as a matlab most common content areas, can acquire)

说明：  高动态GPS中频信号模拟器的关键技术研究,包括从信号的构成到信号模型的搭建，用matlab仿真出来。(The high dynamic GPS intermediate frequency signal simulator s key technologies research, including from the signal constitution to the signal model s build, comes out with the matlab simulation.)
