在研究了JTIDS信号特点和扩频信号检测技术的基础上,分别对空间互谱检测法、二次功率谱检测法和平方倍频检测法进行了理论分析,通过Matlab仿真,给出了JTIDS的时域和频域波形,并比较了三种方法对JTIDS信号的检测性能,得出了平方倍频检测法更适合JTIDS信号的检测的结论。5...
The MATLAB simulation is utilized to evaluate the effectiveness of the proposed method. The experimental results of the complete suppression of the mirror frequency and the correct constellation show that LPI has been accurately estimated and compensated with the appropriate compensation structure.Meng Jie...

This yields empirical evidence on instability periods and reveals various changes and breaks in the causality relationships for the data available from recent years. Moreover, we introduce a comparison with Gaussian wavelets and use the MATLAB software suite for computing, taking the scale instead of...
timestamps in the EEG. The preprocessing of EEG data is summarized below. Notch filters at 51 Hz and 49 Hz were applied to filter out the power line noise. EEG signals were then high-pass filtered with a cutoff frequency of 0.3 Hz using the Matlab function ‘filtfilt’ and a 4th-...
MatlabFull montage EEG recordings of 15 ICU patients (altogether 23 recordings) were analysed to find EEG correlates of delirium. CAM-ICU assessment results were used as the reference. Time period from 7 to 30 minutes at the beginning of the recordings was analysed in 10 sec segments with 5 ...
对于第一个例子，采用由10Hz和75Hz的时域振荡组成的两个信号，信号持续时间为 6 秒，采样频率为1000 ...
