干扰环境中短波通信传输性能研究

Research on Transmission Performance of Shortwave Communication in Interference Environmen

短波通信深受外界干扰影响,尽管已有许多通信抗干扰手段用于缓解干扰对传输的影响,但终究不能使传输性能恢复到正常水准,因此如何更有效地使用这受限的传输能力成为一个重要课题。鉴于无线信道的时变特性,使用一种联合子包与抗干扰手段的自适应机制,并给出了以吞吐率作为优化目标的切换阈值。

Shortwave communication is deeply affected by external interference.In order to mitigate the impact of interference on transmission,various communication anti-interference techniques have been developed.However,these techniques cannot fully restore the transmission performance to normal levels.Therefore,it becomes crucial to explore more effective ways of utilizing the limited transmission capacity.Considering the time-varying nature of wireless channels,an adaptive mechanism that combines sub-packet and anti-interference techniques is employed,and the switching threshold with throughput as the optimization objective is given.
