系统辨识函数的介绍，包括最小二乘法，和辅助变量法(Introduction to system identification function, including the least squares method, and the instrumental variable method)

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。 (failed to translate)
