相关算法的应用很广，例如噪声中信号的检测，一个信号经过一段延迟后自身的相似性，信号中隐含周期性的检测，信号相关性的检验，信号时延长度的测量，滤除确定性信号中的随机干扰信号等等。相关函数还是描述随机信号的重要统计量。

利用CCS5000的集成开发平台，通过C语言对一正弦信号和一余弦信号进行了相关算法设计、编程和分析，然后将其置于CCS集成开发环境下,编译、调试、运行.-correlation algorithm used widely, such as noise signal detection, a signal after a delay after their similarities, implied cyclical signal detection, signal relevance of the test, Signal delay length measurement, signal filtering uncertainty of random interference signal, and so on. Correlation function is described random signal of the important statistics. CCS5000 use integrated development platform C language of a sinusoidal signal and a cosine signal a correlation algorithm design, programming and analysis, then placed CCS integrated development environment, compiler, debugger, run.
