It is a story of humanity coming to an end and everyone pinning their hopes on a group of astronauts who go out to explore space and spread humanity to another planet.
On the sending end, the paper focuses on Error Control Coding, Waveform Shaping, Spread Spectrum and 8PSK modulation, etc.
在发送端，主要研究了差错控制编码，波形成形、扩频和8PSK调制等关键技术；

In the end, based on this method simulation is given for the finishing rolling natural spread model of Baosteel 2050, the results show that the methods proposed in the paper are feasible.
