数字频带通信系统 输入：首先输入模拟信号，给出此模拟信号的时域波形。 数字化：将模拟信号进行数字化，得到数字信号，可以选择PCM编码。 调制：可以选择简单的二进制数字调制方式。例如振幅键控(2ASK)、相移监控（2PSK）、频移键控（2FSK）、差分相移键控（DPSK）等。要求每个题目至少选择两种调制方式。有能力的同学也可以选择其它高效的调制方式?例如多进制数字振幅键控等?给出调制后信号的时域波形。 信道：假定信道属于加性高斯信道?或自行设计。 解调：相应的2ASK、2PSK、2FSK、DPSK解调，仿真获得解调输出波形。 PCM解码：给出解码后的模拟信号的时域波形，并与输入信号进行比较。 系统性能分析：比较在不同调制方式下，该数字频带传输系统的性能指标，即该系统的输出误码率随输入信噪比的变化曲线。(Digital frequency band communication system)

用LMD方法对大坝变形数据进行分解，分解出不同的分量，特别是单调的时效分量，用来判断大坝的变形趋势(The LMD method is used to decompose the deformation data of the dam, and the different components are decomposed, especially the monotonous aging component, which is used to judge the deformation trend of the dam.)
