说明：  对正弦信号自相关和互相关运算的实验。在进行算法模拟时首先应对一个实时数字信号处理的任务选择一种方案和多种算法，用计算机高级语言如（c、Matlab等工具)验证算法能否满足系统的性能指标；然后从多种信号处理算法中找出最佳或准最佳算法。
(right sinusoidal signal autocorrelation and cross correlation of the experimental operation. Conducting simulation algorithm deal with a first real-time digital signal processing tasks to choose a variety of programs and algorithms, Senior computer language such as (c, Matlab, and other tools) verification algorithm can meet the performance indicators; Then from a variety of signal processing algorithms to find the best or potential best algorithm.)
