基于Spinal码的编码协作

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。

Coded cooperation based on Spinal codes

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 forward.Then, on the basis of CC-SPSC, by introducing the strategy regarding the base station as the control center because of its advantages in equipment condition and centralized scheduling, the schems of CC-SPSC-BSC-AL (coded cooperation with selected passes of Spinal codes and base station control-altruism) and CC-SPSC-BSC-SR (coded cooperation with selected passes 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, especially, the CC-SPSC in analog channels and the CC-SPSC-BSC-SR in digital channels have the prominent application advantages.
