dsb-am
使用MATLAB对DSB-AM进行仿真:双边带幅度调制的过程以及对其中所包含的对信号的频谱分析都可以通过MATLAB中的M语句及相关函数来实现。假如信号m(t)=cos(m)以dsb-am方式调制载波c(t)=cos(20*pi*t),所的信号为y(t),并将采样频率定为 fs=100Hz,则可在MATLAB中设计程序对该幅度调制的结果进行仿真,绘制已调信号波形和频谱分析。(It is a example for DSB-AM based on MATLAB .)

SECPSO
二阶粒子群,比pso更加精确更加灵敏地优化函数。在标准pso算法中,微粒的飞行速度仅仅是微粒当前位置的函数,而二阶粒子群算法中微粒飞行速度的变化与微粒位置的变化有关(Second swarm, more sensitive and more accurate than pso optimize function. Pso algorithm in the standard, the particle particle flight speed is only a function of the current position, the second particle swarm flying speed of particles in the particle changes related to changes in the position)

bianyi4_2
编写一通用的预测法分析程序,要求有一定的错误处理能力,出错后能够使程序继续运行下去,直到分析过程结束。可通过不同的文法(通过数据表现)进行测试。(Write a generic prediction analysis procedure that requires a certain degree of error-handling capabilities, enabling the program to continue after an error to run it until the end of the analysis process. Can be tested by different grammar (by performance data).)
