Then cumulant invariants are used to classify bandlimited MPSK signals. The method can work with lower SNR.

并利用此基带序列的高阶累积量构造分类特征不变量，在宽信噪比范围内实现了带限MPSK信号的调制分类。

A CW carrier signal, generated by Agilent Signal Generator, is transmitted to the subject, which reflects the modulated waves to the receiver antenna. The Agilent Spectrum Analyzer, with an under-conversion module inside, demodulates the received signal to 70MHz IF signal, which is then sampled by a ADC module in Agilent Vector Signal Analyzer. Digital quadrature demodulation is used to convert IF signal to baseband. We could finally get the respiration and heartbeat signal by further analyzing the baseband signal.

该系统由信号发射器产生载波，通过天线发射到被测物体；频谱分析仪内置的下变频模块将由物体反射回来的信号下变频到70MHz中频；中频信号经矢量信号分析仪采样，然后经过数字正交解调变频到基带信号；对基带信号进行滤波、FFT等进一步的数字信号处理后即可获得探测的心跳和呼吸信号。

ABSTRACT The aim of the project is to prepare the high temperature superconducting thin films which can satisfy the need of future applications in the field of power transmission. By using biaxially textured Ni (001) and Ag (110) as substrates, the YBCO films with high critical current were obtained under the optimized deposition conditions. Some results were obtained as follows: We developed a simple approach to prepare YBCO films doped with Ag nanograins.
