关于boost库的开发，使用的知道教程。里面的内容很详细，说明都有，适合新手使用。(Know about the boost library development, the use of the tutorial.The inside of the content is very detailed description, all have, suitable for beginners to use.)

数字基带系统将数字信号从时域上看时数字滚降，需要画出滚降前后的波形展示出来。频域上带宽变化了。输入滤波器之前的波形与采样判决之后的波形。采样判决前的频谱。 采样判决后的码型。 2、眼图（采样判决之前的眼图）（信噪比大眼图清晰） 3、误码曲线，（横坐标时信噪比，纵坐标时误码率） 4、Arfa变化对误码特性的影响，变好还是变差(变好)，眼图清晰度变化（清晰），传递函数的带宽的变化。（带宽越大）(1.Digital baseband system point of view the digital signal from the time domain when the number of roll-off, you need to draw the waveform displayed before and after the roll-out. The frequency domain, the bandwidth change. Input filter and sample ruling before the wave after wave. Sample pre-judgment spectrum. Sampling pattern after the verdict. 2, the eye diagram (eye before sampling decision) (SNR big eye clear) 3, the error curve (abscissa when the signal to noise ratio, bit error rate when the vertical axis) 4, Arfa impact of change on BER performance, get better or worse (getting better), change of eye-definition (clarity), the transfer function of the bandwidth changes. (The greater the bandwidth))

假设已经获得不同目标类型的一组特征值，这是可以通过模糊聚类获取哥哥目标类型在特征空间商的聚类中心，当测量到某个目标的特征值，可以通过计算目标特征为止与各个聚类中心之间的距离来判定目标的类型。(matlab fcm)

利用duffing振子检测微弱信号频率的matlab程序。可以检测与周期策动力频率相差0.03之内的微弱信号频率。信噪比达到-68db(use Duffing oscillator frequency detection of weak signals in Matlab procedures. Can be detected with the cycle driven frequency difference of 0.03 within the weak signal frequency. Signal-to-noise ratio-68db)

关于反馈线性化的S函数文件 可修改应用到自己的程序中去(On the feedback of the linear S-function file)
