查询词典 data transmission

The transmitter updates the modulation mode, chooses the optimal transmission vector adaptively and retransmits data automatically by outdated feedback information.

推导了系统在时延反馈条件下的频谱效率和中断概率的闭合表达式，分析了时延反馈对于系统性能的影响。

In order to improve the transmission reliability of data and image in 3G, the channel coding technology-HARQ combined by ARQ and FEC is often adapted widely.

为了提高第三代移动通信中数据和图像的传输可靠性，常采用ARQ和FEC相结合的HARQ信道编码技术。

Therefore,the reliability of data and image transmission is usually improved using hybrid ARQ error control scheme which is combined by ARQ and FEC.

因此为了提高数据及图像传输的可靠性，人们提出了采用ARQ与FEC相结合的混合ARQ差错控制方案。

The existing common carrier network for transmission while providing added data service features with separate equipment.

一种计算机网络，利用现有的公用载波网络进行传输，同时使用独立的设备提供附加的数据服务功能。

A computer network which utilizes the existing common carrier network for transmission while providing added data service features with separate equipment .

一种计算机网络，利用现有的公用载波网络进行传输，同时使用独立的设备提供附加的数据服务功能。

Optical fiber communication is transferring form point-to-point transmission to mesh network. Traditional optical-electronical-optical transformation limits the data rate and adds the cost. With reconfigurable optical add/drop multiplexer for signal switching and routing, the OEO transformation can be bypassed, reduceing equipment size and cost.

光纤通信由点到点传输向网格化发展，传统的光—电—光转换过程限制了通信速率并导致成本增加，采用可重构光分叉复用器进行光交换和光路由，可以省去光—电—光转换过程，缩小尺寸和降低成本。

This brought fixed cost, but it also is meant at the same time use a source to won't make you singlehanded assume a problem.

这带来了一定的成本，但它同时也意味着使用开源不会让你独力承担问题。
