循环平稳算法估计载波频率程序，对BPSK效果好，(Estimation of carrier frequency program by cyclostationary algorithm)

说明：  这是工业经常用到的模糊自整定的PID，具有很强鲁棒性，而且控制器容易设计(This is a frequently used industrial fuzzy self-tuning of PID, are highly robust, and easy to design controllers)

该算法时LDPC码优化的好帮手。通过差分进化（DE）实现LDPC码度分布优化。给定码率，自动搜索最佳度分布。算法运算量较小，可以得到次优解。(The algorithm of LDPC code optimization is a good helper. Through differential evolution ( DE ) to realize LDPC code degree distribution optimization. Given rate, automatic search of optimal degree distribution. Algorithm can get smaller, suboptimal solution. )
