One of the key technologies of deep space communication is channel code . there are differences between deep space communication and the common space communication . because the former one has some characteristics , such as extending information transmission , and seriously reducing signal energy , it is necessary to ensure the information transmission band and the exactness by using the special means 信道编译码是深空通信中的关键技术之一,深空通信与一般的空间通信不同,深空通信具有信息传输时延大、信号能量衰减严重等特点,必须有特殊的手段保证其信息传输的带宽和准确。
