摘要:

针对远海岛礁远离本土能源供给严重受限及环境监测缺乏低成本、高可靠的远程传输手段问题,依托陆地广泛分布的移动通信基站,提出一种基于广域协作接收的天波超视距接入网络传输框架,从物理层、网络层、感知层3个方面分别解决远海岛礁环境监测天波超视距传输面临的信道衰落、链路非对称与频谱拥挤问题。典型天波信道环境下链路传输波形与多通道融合算法的仿真结果表明,只需要通过3个接入节点的协作接收,即可保障3 000 km范围内远海岛礁低功率电台的可靠接入,对国家远洋船舶监测、边防交通隘口监测等也有一定的参考价值。

Abstract:

In view of the serious limitation of local resource supply for remote island and reef and the lack of low cost,high reliability long-distance transmission methods for environmental monitoring,relying on the mobile communication base stations widely distributed on the land,an over-the-horizon(OTH) skywave access network based on wide-area cooperative reception was proposed.The problems of channel fading,link asymmetry and spectrum congestion faced by remote island and reef environments monitoring for an OTH skywave transmission were solved from three aspects:physical layer,network layer and perceptive layer.The simulation results of the lower link transmission waveform and the multi-channel fusion algorithm in the typical skywave channel environment show that the reliable access of low-power transceiver in the remote island and reef within a range of 3 000 km could be guaranteed only through the cooperative reception of three access nodes.There was also some reference to monitoring of national ocean-going ships and border defence traffic pass monitoring.

Key words: sky wave stadia communication, remote island and reef, wide area collaboration, multi-channel fusion
