面向无人机通信的乘性重复CC-HARQ研究
Research on Multiplicative Repetition CC-HARQ for UAV Communication
摘要
Abstract
UAV vehicle communication is currently a hot topic in communications.In practice,UAV communication is suscepti-ble to complex and variable electromagnetic interference.To achieve high-throughput and reliable communication,this paper proposes a Chase Combining Hybrid Automatic Repeat Request(CC-HARQ)transmission strategy based on multiplicative repetition for non-bi-nary codes.By performing multiplicative repetition operations on the retransmitted non-binary codeword sequences before sending them,the reliability of the system transmission can be improved,and the risk of UAVs being detected during mission execution can be low-ered.In order to maximize system throughput,this paper designs an intelligent optimization algorithm for the selection of multiplicative factors.Simulation results show that compared with traditional CC-HARQ transmission,the CC-HARQ transmission scheme based on multiplicative repetition has a better bit error rate and throughput performance.关键词
