基于多相结构的信道化发射机实信号输出matlab仿真程序:从仿真得到的图可以看到，输出8路实信号所需的带宽为输出8路复信号所需带宽的一半。另外，输出的复信号频谱结构不再像直接法实现时所得到的顺序对应结构，其原因还有待进一步研究。(Channel based on multi-phase structure of real signal of the transmitter output matlab simulation program: graph obtained from the simulation can be seen, the output 8-channel bandwidth needed for real signals, the output 8-channel half the bandwidth required for complex signals. In addition, the output structure of the complex signal spectrum is no longer realized as the direct method corresponds to the order obtained by the structure, the reason remains to be further studied.)
