使用MATLAB软件，在高斯信道下，对信号进行采样，分析，输出曲线图-use the MATLAB to putout the ber

考虑你在哪里不同的传感器，桥上两侧的汽车造成的振动记录收集数据的情况。当你分析这些信号，则可能需要对齐。假设你有3个传感器以相同的采样速率工作，他们是造成同一事件的测量信号。-Consider a situation where you are collecting data different sensors, recording vibrations caused by cars on both sides of a bridge. When you analyze the signals

对有白噪声污染的余弦信号进行采样，通过傅里叶变换对其频率成分进行分析。(The cosine signal contaminated by white noise is sampled, and its frequency components are analyzed by Fourier transform.)
