【摘要】：現有海上船舶通信系統帶寬窄、頻帶利用率較低,同一時刻能夠建立的上行和下行鏈路數量有限,隨著船舶數量的增多及任務執(zhí)行頻率的增加,現有的通信系統容量已經成為船舶通信的瓶頸。WIMAX技術作為最新的第4代無線通信技術,具有頻帶利用率高、頻率覆蓋范圍廣以及和現有船舶通信系統兼容的特性,能夠擴展現有通信系統的信道容量。本文在研究現有的船舶通信系統及海上環(huán)境特性的基礎上,給出基于WIMAX的海上無線網絡規(guī)劃算法,并進行仿真。
[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.
