发布时间：2019-05-17 12:52
【摘要】：现有海上船舶通信系统带宽窄、频带利用率较低,同一时刻能够建立的上行和下行链路数量有限,随着船舶数量的增多及任务执行频率的增加,现有的通信系统容量已经成为船舶通信的瓶颈。WIMAX技术作为最新的第4代无线通信技术,具有频带利用率高、频率覆盖范围广以及和现有船舶通信系统兼容的特性,能够扩展现有通信系统的信道容量。本文在研究现有的船舶通信系统及海上环境特性的基础上,给出基于WIMAX的海上无线网络规划算法,并进行仿真。
[Abstract]:The bandwidth of the existing marine ship communication system is narrow, the frequency band efficiency is low, and the number of uplink and downlink that can be established at the same time is limited. With the increase of the number of ships and the frequency of mission execution, The existing communication system capacity has become the bottleneck of ship communication. WiMax technology, as the latest fourth generation wireless communication technology, has the characteristics of high band efficiency, wide frequency coverage and compatibility with the existing ship communication system. It can expand the channel capacity of the existing communication system. On the basis of studying the existing ship communication system and the characteristics of marine environment, this paper presents a maritime wireless network planning algorithm based on WIMAX, and simulates it.
