matlab
实上,我们可以把系统框图中外编码器、交织器和内编码器三部分级联后的总体,看作一个级联码的编码器,同理,外译码器、去交织器和内译码器三部分级联后的总体构成了级联码的译码器。
本次仿真外编码采用(7,4)HAMMING码,内编码采用(2,1,3)卷积码。交织编码采用(7,4)卷积交织编码或循环等差交织编码。除特别说明外,交织编码采用前者即(7,4)卷积交织编码。

curve-combine
MATLAB提供了各种曲线拟合方法,例如:Exponential, Fourier, Gaussing, Interpolant, Polynomial, Power, Rational, Smoothing Spline, Sum of Functions, Weibull等,当然,也可以使用 Custom Equations.
cftool不仅可以绘制拟合后的曲线、给出拟合参数,还能给出拟合好坏的评价参数(Goodness of fit)如SSE, R-square, RMSE等数据,非常好用。但是如果我们已经确定了拟合的方法,只需要对数据进行计算,那么这种GUI的操作方式就不太适合了,比如在m文件中就不方便直接调用cftool。
(matlab has given a lot of method for curve combine ,we will give a new method and provide a matlab code.)
