这是关于如何使用MATLAB的一个PPT，希望对大家有帮助(failed to translate)

the day of year是指这一年已经逝去的天数（包括当天） 。在平年中，它的取值范围为 1 到 365，在闰年中，它的取值范围 1到 366。编写一个 MATLAB 程序，输入年，月，日， 输入为对应的 the of year。 (the day of year is the year the number of days have been lost (including the day). In the average year, it ranges from 1 to 365, in a leap year, it ranges from 1 to 366. Write a MATLAB program, enter the year, month, day, enter the corresponding the of year.)

matlab程序，一种快速ICA算法，用于混合信号盲分离，可应用于通信系统信号处理(matlab program, a fast ICA algorithm for blind separation of mixed signals, signal processing can be used in communication systems)

用burg算法实现功率谱的估计，可以改变信噪比SNR，阶次P，可以分析分辨率(Burg algorithm using power spectrum estimation, can change the signal to noise ratio SNR, order P, can be analyzed resolution)

该文档时一个宽带信号处理的源代码，被验证是成功的，可以供学习练手(The document, a broadband signal processing, source code, to be verified to be successful, you can study and practice for hand)

快速傅里叶变换在Matlab环境下的实现(Fast Fourier Transform in Matlab environment to achieve)

这里的k-means聚类，是事先给出原始数据所含的类数，然后将含有相似特征的数据聚为一个类中。(Where k-means clustering, is given in advance the number of classes contained in the original data, then the data contained similar characteristics grouped into a single class.)

本文主要是描述的DDC的matlab功能，从输入的信号经过1/4fs搬频，然后半带抽取，再到混频，最后到分数倍的抽取，再经过成形滤波器输出。(digital down convention)
