中继

It is a relay system.

它是一个中继系统。

They must rely on a relay server.

他们必须依赖于一个中继服务器。

One day it is a frame relay switch, the next it is your ISDN router.

这一天是帧中继交换机，这是你们未来的ISDN路由器。

L( r" s# Z: X2 p) Z- Q0 c- r If you are planning to run in Sysop mode, put an -R or -L at the end of your call to indicate a "repeater" or "link, respectively (for example, K1RFD-L). Use -L to denote a simplex link, or -R if the link is tuned to the frequency pair of a local repeater.

如果用户计划使用系统操作模式，则需要在呼号后加L或R，以表示连接或中继（例如：BG1KLS-L）。L代表直发连接，而R代表用户将Echolink的连接调到本地中继相同的上下行频率。

In this paper, subcarrier pair selection and power allocation in broadband OFDM relaying system is addressed.

该文研究宽带OFDM中继系统的最优中继子载波对选择和功率分配。

Both repeaters are in this case, for example, so-called alternating slot repeaters.

例如，两个中继器在这种情况下，就是所谓的交替时隙中继器。

We've had repeaters linking to other repeaters, in the past using purpose built radio links with directional antennas.

我们已经让中继器连接到其他中继器，在过去使用的目的是为了建立无线电与定向天线连接。

A joint optimization strategy for relay selection and power allocation is proposed to optimize the performance of cooperative communication system.

为了优化协作通信系统的性能，提出了一种基于信道容量增益的中继节点选取策略，并在此基础上提出了源节点和中继节点最优功率分配算法。

The wireless transmission uses data relaying to enhance the signal and dynamically set relay substation by statistical met...

在无线传输中，采用数据中继方式实现数据信号增强，并用统计法动态配置中继子站，优化了通信网络。

The key idea is to obtain benefits of multi-antenna systems by cooperative retransmissions among relay stations and users when considering protocol layers.

提出时分多址方式下由固定中继节点支持的透明模式下的随机接入协议，通过中继节点与用户间的合作重传来解决多个用户同时接入发生碰撞的问题。

However, as the name（read－only memory）implies, CD disks cannot be written onorchanged in any way.

然而，正如其名字所指出的那样，CD盘不能写，也不能用任何方式改变其内容。
