Designs a linear phase FIR lowpass filter such that it: - minimizes the filter order - has a constraint on the maximum passband ripple - has a constraint on the maximum stopband attenuation (This is a quasiconvex problem and can be solved using a bisection. minimize filter order n s.t. 1/delta <= H(w) <= delta for w in the passband |H(w)| <= atten_level for w in the stopband where H is the frequency response function and variable is the filter impulse response h (and its order/length). Data is delta (max passband ripple) and atten_level (max stopband attenuation level). )

用saleh模型拟合功率放大器，采用n组功放的输入输出数据标识模型中的参数，拟合功放输入输出曲线(Fitting power amplifier with Saleh model. The input and output data of N group power amplifier are used to identify the parameters in the model, to fit Input and output curve of fitted power amplifier.)

CODE是寫利用FUZZY的方式來做分群,也就是有歸屬度的程度分別 ,個人覺得比硬式分群結果來的較好,最後會畫圖來顯示結果.(CODE is written using FUZZY way to do grouping, which is a degree of attribution degrees, respectively, than the rigid grouping personally feel better the results will finally drawing to show the results,)
