【摘要】：隨著第四代通信技術的逐漸成熟，它所具有的高速度，高兼容性和高靈活性等特點使人們的生活變得更加便利，然而現今更多的是將其運用在陸地通信系統(tǒng)。對于海洋面積約占地球總面積71.8%的現狀，如何開發(fā)海洋資源，如何完善海上通信，完成更好的海上信息交互成為科學家以及運營商關注的重點�，F有的海上通信系統(tǒng)存在諸如頻率數量有限，容納的用戶非常少，通信延遲大，不利于進行語音通信等弊端。相比之下，4G通信技術的優(yōu)勢便顯現無疑，若可將其應用于航海通信上，定會使海上通信走向新的篇章。 本文首先對WiMAX和LTE技術進行介紹和對比，然后對基站搭建方法和原則進行相應的闡述。將網絡規(guī)劃原則與近海水域的特點相結合，總結出影響近海水域無線網絡規(guī)劃的因素。結合海上信道的特征，考慮海面反射，大氣吸收，船體穿透等因素對于電波傳輸時所造成的損耗，總結出一個海上電波傳輸損耗模型。參照當今的WiMAX和LTE設備的參數，計算出基站不同高度可以理論覆蓋的通信半徑。對上海港近海區(qū)域的島嶼狀況進行分析，使用EXata軟件進行場景的搭建，最大程度的復制海上的信道環(huán)境并對此場景進行仿真。加載上海港近海領域的三條航道，并針對每條航道提出了兩種不同的基站搭建方案，分別使用WiMAX和LTE技術運行場景，統(tǒng)計出在不同場景中船只通信的收包率和端對端延時。首先在兩種技術內橫向對兩種基站搭建方式進行比較選出最佳方案，，再縱向對兩種技術的最佳方案進行分析。最終得出在近海水域通信中，LTE技術相比于WiMAX技術在性能上更具優(yōu)勢，但同時搭建維修費用也更為巨大；在島嶼狀況簡單的情況下首選LTE技術，而島嶼情況復雜時，采用WiMAX技術也不失為一種好的選擇。
[Abstract]:With the maturity of 4th generation communication technology, its high speed, high compatibility and high flexibility make people's life more convenient. However, nowadays, more and more of them are used in land communication system. How to develop marine resources and how to perfect maritime communication for the present situation that the ocean area accounts for about 71.8% of the earth's total area. To achieve better offshore information interaction has become the focus of attention of scientists and operators. Existing offshore communication systems such as limited frequency, very few users, communication delay. The advantage of 4G communication technology is obvious, if it can be applied to maritime communication, it will lead to a new chapter in maritime communication. This paper first introduces and compares the WiMAX and LTE technologies, and then expounds the methods and principles of the base station construction, and combines the network planning principles with the characteristics of the offshore waters. Combined with the characteristics of the offshore channel, considering the sea surface reflection, atmospheric absorption, hull penetration and other factors caused by the loss of radio wave transmission. A loss model of radio wave transmission at sea is summarized. The parameters of today's WiMAX and LTE equipments are referred to. Calculate the communication radius which the base station can cover with different heights. Analyze the island condition in the offshore area of Shanghai Port and use EXata software to build the scene. Copy the channel environment of the sea to the greatest extent and simulate the scene. Load the three waterways in the offshore area of Shanghai Port, and propose two different base station construction schemes for each channel. Run scenarios using WiMAX and LTE technologies, respectively. The packet receiving rate and end-to-end delay of ship communication in different scenarios are calculated. Firstly, the best scheme is selected by comparing the two base stations in two different technologies. Finally, compared with WiMAX technology, LTE technology is superior to WiMAX technology in performance, but at the same time, the cost of building and maintenance is more huge. In the case of simple island condition, LTE technology is preferred, and when island condition is complex, WiMAX technology is also a good choice.
