退火算法，能够良好的处理数据，避免局部的最优值，因为添加了遗传算法(Annealing algorithm, can be a good deal of data, to avoid the local optimal value, because of an genetic algorithm)

this program is hep full o analyse the multilevel inverter

最小频移键控（Minimum Shift Keying，MSK）是一种具有连续相位和最小频偏的数字调制技术。MSK的突出优点是信号具有恒定的包络和信号的相位连续性，频带利用率高，信号的功率谱在主瓣外衰减较快，这就使得它对邻波道干扰小。(MSK (Minimum Shift Keying) is a continuous phase and the minimum deviation of the digital modulation techniques. Outstanding advantage of MSK signals have constant envelope and continuous phase signals, high bandwidth efficiency and the signal power spectrum decreases rapidly outside the main lobe, this makes it a small adjacent channel interference.)
