Cross-layer design in HF communications with the consideration of IP service features

Abstract

So far, the high-frequency (HF) time-varying channel was always the development obstacle for HF data communication. A cross-layer system based on AMC and hybrid ARQ (HARQ) in HF IP communication was proposed to overcome the problem. In order to adapt the changing of the HF channel, the HARQ feedback message was used to transfer the modulation mode and coding mode which was decided by the receiver. And the IP frame average server time was made as the performance index of the system which could rise up the performance of IP service feature. The general closed-form expression of the IP frame average server time had been given. What was more, the advantages of the system have been proved in other queue performance about IP frame through theoretical analysis and simulation researches.
