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)是未來高速全光通信網絡的備選方案之一,是目前光通信技術領域研究的熱點。
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 擴頻通信技術具有優越的抗干擾、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,目前廣泛應用于移動通信、雷達、導航、測距、電力線通信等領域。
code division multiplexing meaning:[Computer] < communications > (CDMA) (Or "spread spectrum") A form of multiplexing where the transmitter encodes the signal using a pseudorandom sequence which the receiver also knows and ...
