《射频电路设计——理论与应用》一书课后习题第四章Matlab程序代码("RF circuit design-- Theory and Application," a book chapter IV Swimming Exercises Matlab code)

通过MATLAB来实现天线的一维，二维，三维的方向图，十分方便使用(MATLAB to implement the antenna by one-dimensional, two-dimensional, three-dimensional pattern, very easy to use )

基于统计模型（CS）的IMM-kf，程序简单实用(Based on statistical models (CS) of the IMM-kf, simple and practical procedure)

matlab里面的图形编辑 潮流的调和分析(matlab inside the trend of harmonic analysis and graphics editing)

产生不同频率、不同幅度的两种正弦波信号 对两个信号进行叠加并做频谱分析 还原原来两个信号（LPF)(Produce different frequency, the two sine wave signals of different magnitudes of the two signals are superimposed and do spectral analysis to restore the original two signals (LPF))

adaptive equalization for decision feedback equalizer

DTMF goertzel function, it is really helpful for other beginners who want to do the DTMF

说明：  程序中 时间结点错开了一个位子； （2）没有注意保存中间结果，程序画出的只是之后一个小时间段结果。(Staggered in time node program a seat (2) lack of attention to hold intermediate results, the program just to draw a small period of time after the results.)

本人所传是周期图代码,希望能够对大家能有所帮助.(my map-cycle is code, we hope to be able to help.)
