一種衛(wèi)星波分復(fù)用/黑碼分多址組網(wǎng)方案研究

介紹了組建衛(wèi)星光通信網(wǎng)絡(luò)的必要性，分析比較了衛(wèi)星光通信網(wǎng)絡(luò)中可采用多址技術(shù)及其特點。結(jié)合波分復(fù)用技術(shù)和光碼分多址技術(shù)的優(yōu)點，提出一種新的光碼分多址+波分復(fù)用組網(wǎng)方案，給出了該組網(wǎng)方案的網(wǎng)絡(luò)結(jié)構(gòu)及編碼實現(xiàn)方案，并分析了該種組網(wǎng)方案的特點和應(yīng)用前景。結(jié)果表明，該混合組網(wǎng)方案可很好地利用波分復(fù)用和光碼分多址技術(shù)的優(yōu)點，具有網(wǎng)絡(luò)拓?fù)浣Y(jié)構(gòu)靈活、易于擴展、可承載多種業(yè)務(wù)以及易于實現(xiàn)的特點，在衛(wèi)星光通信網(wǎng)絡(luò)中具有重要的應(yīng)用價值。The characteristics of different access techniques used in optical network are analyzed and compared. A new optical network with Wavelength Division Multiplexing and Optical Code Division Multiplexing Access (WDM/OCDMA) is presented. The advantages and applications of this network scheme are discussed. In the end, the network structure of this WDM/OCDMA network and the optical CDMA encoding and decoding schema are introduced. The results show that the WDM/OCDMA network, which can fully use the advantages of WDM and OCDMA technologies, is valuable in practice.
