Optical code division multiplexing access ( ocdma ) is one of the possible resolutions for all optical communication network in the future, which is a hot topic in optical communication research 光碼分多址ocdma(opticalcodedivisionmultipleaccess)是未來(lái)高速全光通信網(wǎng)絡(luò)的備選方案之一,是目前光通信技術(shù)領(lǐng)域研究的熱點(diǎn)。
Spread spectrum technique, which can handle variable adverse environments, exhibits unique qualities that have a number of advantages in anti-jamming, anti-noise, reduction of multi-path interference, low power spectral density, privacy, selective addressing and code division multiplexing 擴(kuò)頻通信技術(shù)具有優(yōu)越的抗干擾、抗噪音、抗多徑衰落性能,能在低功率譜密度下工作,具保密性、可多址復(fù)用和任意選址,能有效克服各種惡劣的信道特性,目前廣泛應(yīng)用于移動(dòng)通信、雷達(dá)、導(dǎo)航、測(cè)距、電力線通信等領(lǐng)域。
