摘　　要：针对5G的高速率传输需求,研究了基于Spinal码的编码协作。基于Spinal码的无速率性,提出了直接选用不同通道内所有编码符号实现编码协作的CC-SPSC方案。在此方案基础上,考虑基站在设备条件和中心调度方面的优势,引入以基站为控制核心的策略,提出了CC-SPSC-BSC-AL方案和CC-SPSC-BSC-SR方案。仿真结果表明,所提方案在模拟信道和数字信道下均有显著的误码率性能提升,尤其是CC-SPSC和CC-SPSC-BSCSR方案,分别在模拟信道和数字信道下的应用优势突出。In view of 5G communication systems＇ high rate transmission demand, the coded cooperation based on Spinal codes was studied. According to the rateless characteristic of Spinal codes, a scheme for coded cooperation （CC） with selected passes of Spinal codes （SPSC） , called the CC-SPSC, was put torward. Then, on the basis of CC-SP- SC, by introducing the strategy regarding the base station as the control center because of its advantages in equip- ment condition and centralized scheduling, the schems of＇ CC-SPSC-BSC-AL （coded cooperation with selected pas- ses of Spinal codes and base station control-altruism） and CC-SPSC-BSC-SR （coded cooperation with selected pas- ses of Spinal codes and base station control-self regard） were proposed. The simulation results shows that all three schemes can significantly improve the bit error rate performance in both digital channels and analog channels, espe- cially, the CC-SPSC in analog channels and the CC-SPSC-BSC-SR in digital channels have the prominent applica- advantages.
