multiplexing

a channel derived by time division multiplexing.

一种按割成多路用的道

Dense Wavelength Division Multiplexing (DWDM) is an available technology, which can greatly increate the message capacity.

近年来随着光通的飞速发展，密集波用技术(DWDM)已成为解决大容量息传输的有效手段。

The uncoded orthogonal frequency division multiplexing (OFDM) systems do not have multipath diversity, and the diversity order is only one in the multipath Rayleigh fading channel.

本研究提出一指标的机制与方法，藉以评估虚拟量测系统的度。

OFDM (Orthogonal Frequency Division Multiplexing) is a method that can combat multipaths, fully use the frequency band and has high data rate, and has a promising future in UWA communication.

摘要正交频用(OFDM)技术具有抗多径、频带利用充、传输数据率高的优点，在水声通中具有重要的发展前景。
