用带反馈通道的移位寄存器产生PRBS序列信号。要选择合适的通道，经模二加法后进行反馈。在程序中，移位寄存器个数可从2到13中任意选择，其长度也可以自由选择。运行结果在vc++的运行环境中能看得很清楚，最后产生的M序列数据也存在相应的数据文件中。-With a shift register with feedback channel PRBS sequence generated signals. To select the appropriate channel, molded after the second addition of feedback. In the program, the number of shift register 13 can be from 2 to choose, free to choose its length. Operation results in vc++ runtime environment, can see clearly, the final sequence data generated by M also the corresponding data file.
