说明：  可变窗宽短时付氏变换算法数字信号时频分析m文件(Variable window width STFT m-files for JTFA)

灰色系统预测源代码,本人亲自试过可用，为什么一定要20个字呢(Grey forecasting the source code )

说明：  粒子群算法优化matlab源代码，效果不错(Particle swarm optimization algorithm optimizes matlab source code, the effect is good)

偏移四相移相键控调制，也就是OQPSK，输出信号为OQPSK调制信号的复包络(Offset four-phase phase shift keying modulation, that is, OQPSK, the output signal for the OQPSK modulated signal complex envelope)

用costas环实现载波同步。假设发送信号载波频率为3.563Mhz，本地初始频率为3.5628Mhz。程序中直接给出了环路滤波器的参数C1,C2。(this is synchoronization on time recovery basing on matlab)

遗传算法是模拟达尔文的遗传选择和自然淘汰的生物进化过程的计算模型。它的思想源于生物遗传学和适者生存的自然规律，是具有“生存＋检测”的迭代过程的搜索算法。遗传算法以一种群体中的所有个体为对象，并利用随机化技术指导对一个被编码的参数空间进行高效搜索。(Genetic algorithm is simulated Darwinian natural selection of genetic selection and evolution process model. It' s thought from biological genetics and survival of the fittest laws of nature, is a " survival+ detection" iterative process of search algorithm. Genetic algorithms in a group all the individuals targeted, and technical guidance on the use of a randomized coded efficiently search parameter space.)
