multiplexing

a channel derived by time division multiplexing.

一种按时间分割成多路用的信道

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

近年来随着光通信的展，密集波分用技术(DWDM)已成大容量信息传输的有效手段。

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.

本研究提出一个信心指标的机制与方法，藉以评估虚拟量测系统的信心度。

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.

摘要正交频分用(OFDM)技术具有抗多径、频带利用充分、传输数据率高的优点，在水声通信中具有重要的展前景。
