psk
- psk调制与解调(加入噪声)。属于通信原理的课程设计。-psk modulation and demodulation (add noise). Communication Theory belong to the curriculum design.
wang
- 单边带调制,加入大噪声和小噪声的区别,可以解调加入噪声的调制信号,观看两种效果,在频域条件下进行比较。注:需要fftseq函数调用。-Single sideband modulation, noise added to the large and small noise difference, you can join the demodulation of the modulation signal noise to watch the two effects, in the frequenc
gaosi-
- 用于通信仿真编程当中,可用此程序为通信信号加入高斯白噪声-For communication simulation programming, use this program for communication signal to join the Gauss white noise
signal_pro
- 对信号加入噪声,绘制频谱图,设计滤波器,对信号进行频谱分析,滤波-The noise signal is added, rendering the spectrum diagram, the design of filters for spectral analysis of the signal, filtering
filters-used-to-heart-noise
- 读取心电数据,画出心电数据的波形和频谱图,观察心电数据的频率段范围 2.分别添加以下噪声(至少3种),画出噪声信号的频谱图,验证设计的噪声是否符合要求 (1)基线漂移 基线漂移通常为频率非常非常低的噪声信号,添加了基线漂移后的心电信号可以观察到原始信号整体的上下浮动 (2)高频噪声 高频噪声可以设计为大于100Hz的随机信号 (3)呼吸噪声 人体的呼吸带来的干扰大约在0.1Hz~0.25Hz (4)50HZ工频信号干扰(必做) 50Hz工频信号
