| 针对短波通信中点对点通信可靠性不高，导致短波无线组网难以广泛有效应用，以至依靠接入基站组网保障区域通信的问题，提出了基于短波第四代自动链路建立（The 4th Generation Automatic Link Establishment,4G-ALE）频谱感知选频技术的协作中继组网（Collaborative Relay Networks,CRN）通信技术，并采用混合自动请求重传（Hybrid Automatic Repeat request,HARQ）和频率分集增强接收可靠性。该协作中继组网可不依托接入基站实现可靠短波无线宽带高速组网通信，数据传输成功率提升30%～300%。 |

| Abstract: |
| For the low connectivity of high frequency(HF) point-to-point communication,HF wireless network is not widely and efficiently applied,so that the fixed relay station is needel to guarantee regional communications.To solve the above problem,the author preseats a HF collaborative relay network(CRN) method based on the 4th Generation Automatic Link Establishment(4G-ALE) is presented,which uses spectrum-awareness to select best communication frequency.The hybrid automatic repeat request(HARQ) and frequency diversity parallel processing are used to enhance reception reliability.The CRN can achieve HF wideband waveforms wireless networking and the throughput is improved 30%～300%. |
