  • 摘要: 無線紫外光通信成為強(qiáng)電磁干擾下的有效通信手段，滿足復(fù)雜戰(zhàn)場環(huán)境下車隊(duì)執(zhí)行戰(zhàn)略物資運(yùn)輸和彈車隊(duì)隱蔽行駛時(shí)車輛間保持可靠隱秘通信的需求。在行駛中每輛車自身作為其它車輛的中繼，通過多跳方式為非視線內(nèi)車輛之間建立穩(wěn)定可靠的通信鏈路。因此，基于紫外光單次散射模型，該文研究了最優(yōu)多跳中繼問題，理論分析了收發(fā)仰角與頻譜效率的關(guān)系，依據(jù)使頻譜效率最大化原則，得出最優(yōu)跳數(shù)近似表達(dá)式。仿真結(jié)果表明，不同距離移位范圍和不同收發(fā)仰角都對(duì)應(yīng)特定的最優(yōu)跳數(shù)值，與最優(yōu)能量計(jì)算方法相比，最大頻譜效率計(jì)算方法在小功率傳輸時(shí)有更好的傳輸能力，并且達(dá)到節(jié)約功率的需求。紫外光長距離通信時(shí)，系統(tǒng)性能并不隨著協(xié)作中繼數(shù)的增加而提高，選取合適的中繼數(shù)及小發(fā)射仰角和大接收仰角的結(jié)構(gòu)配置，系統(tǒng)可獲得較高的傳輸能力。
    Abstract: Wireless ultraviolet communication becomes an effective means of communication under strong electromagnetic interference, which meets the need of reliable and secret communication between vehicles when the fleet performs strategic material transportation and the missile vehicle fleet of concealed driving vehicles in a complex battlefield environment. Each vehicle acts as a relay for other vehicles while driving, and establishes a stable and reliable communication link between non-line-of-sight vehicles through a multi-hop model. Therefore, based on the single-scattering model of ultraviolet, the optimal multi-hop relay problem is studied, and the relationship between the elevation angle of the transmitting and receiving and the spectral efficiency is theoretically analyzed. According to the principle of maximizing the spectral efficiency, the approximate expression of the optimum number of hops is obtained. The simulation results show that the optimum number of hops correspond to different distance shift range and elevation angles. Compared with the optimum energy calculation method, the proposed method has better transmission capability in low power transmission and achieves the requirement of power saving. In the long-distance ultraviolet communication, system performance does not increase with the number of cooperative relays. The system can obtain a higher transmission capacity by selecting a suitable number of relays and a small transmission elevation angle and a large receiving elevation angle.
