中文说明：在编码示例中，请按照下一节中，我们使 (12.126) 的使用。A因此编制 MATLAB 程序进行映射所需的计算符号错误概率对位错误概率，如下所示 ︰
English Description：
In the coding examples to follow in the following section, we make use of (12.126). A MATLAB program is therefore developed to carry out the calculations required to map the symbol-error probabilities to bit-error probabilities as follows:
