代码说明:

说明:  数字信号处理设计与仿真分析 (1)建立两个模拟信号的数学模型 sa1(t)和 sa2(t), 其中 sa1(t)是有用信号, sa2(t)是干 扰信号。 两个信号的中心频率、信号带宽等参数由学生自己选定,要求两个信号的频谱不重 叠, sa2(t)的幅度比 sa1(t)的幅度高 20dB, 两个信号时域叠加得到合成信号 xa(t), 即 xa(t)= sa1(t)+ sa2(t) 设计计算机程序仿真产生 sa1(t)、 sa2(t)、 xa(t)信号, 分别画出三个模拟信号的时域波 形和频谱图;(Establish two mathematical models of analog signals sa1(t) and SA2 (t), where SA1 (t) is the useful signal and SA2 (t) is the dry signal Interference signals.)

    四步搜索算法对三步算法进行了适当的改进,在一定程度上弥补了TSS算法在估计细小运动时的不足,并加入了半途中止的策略,进一步提高了搜索精度 (Four-step search algorithm for three-step algorithm to improve the appropriate, to a certain extent make up for the TSS algorithm in estimating the inadequacy of a small movement, and joined the mid-suspension strategy to further improve the search accuracy)

    灰色理论认为系统的行为现象尽管是朦胧的,数据是复杂的,但它毕竟是有序的,是有整体功能的。灰数的生成,就是从杂乱中寻找出规律。同时,灰色理论建立的是生成数据模型,不是原始数据模型,因此,灰色预测的数据是通过生成数据的gm(1,1)模型所得到的预测值的逆处理结果。(Gray theory that the behavior of the system even though the phenomenon is dim, the data is complex, but still it is ordered, there is a whole function. Gray number generation, that is, from the clutter to find out the laws. Meanwhile, the gray theory is to generate the data model, not the original data model, so gray prediction data by generating data gm (1,1) model predicted values ​ ​ obtained result of the inverse process.)
