说明：  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。
(Used with feedback channel shift register sequence generated PRBS signal. Please select the appropriate channels, by mode after 2 adder feedback. In the process, the number of shift register could be from 2-13 in the arbitrary choice, its length can also be free to choose. Results in vc++ The operating environment can be clearly seen, the last M-series data generated there are corresponding data file.)
