This paper is about the hardware of circuit design for radiocommunication LED display screen,and mainly introduced ist principle and the design about the circuit.

设计了无线通信LED显示板的硬件部分，介绍了LED点阵显示器的驱动电路和无线收发模块电路。

In addition, C-lens and TFFs were passively integrated into the optical bench using V-groove and U-groove structure. The packaging cost can be greatly reduced.

同时V型槽和U型槽之精准定位特性，使三频光收发模组之组装能可以被动对准的方式进行，可大幅降低封装所需成本。

Phan notes that the system automatically reconfigures itself if there is a problem with a hardware channel. Another capability that distinguishes the F-35's communications system from JTRS radios is the ability to schedule, transmit and receive signals that would normally interfere with each other in a time-ordered fashion that avoids co-site issues.

科林。潘指出，系统在遇到硬件通道故障时会自动重新配置。F-35的通信系统区别于JTRS无线电系统的另一个功能是能合理安排收发信号的时机避免相互的信号干扰。

Like all JTRS Operational Requirement Document waveforms in the 2 MHz to 2 GHz frequency range, the UHF SATCOM and HF waveforms can run in any of the GMR system's four reprogrammable Universal Transceivers.

同所有联合战术无线电波形需求在2MHz到2GHz之间一样，超高频卫星通信和高频波形能够在任何车载地基移动无线电系统的四重编程通用收发器中运行。

IP multicast technology is introduced and its communication mode in SCADA system is discussed.With a communication middleware designed,the message receiving and retransmitting mechanism is established to ensure the real-time and reliable communication.

在介绍IP组播技术的基础上，论述了组播技术在SCADA系统中的通信方式，设计一个组播通信中间件，建立报文接收和重传机制，确保信息收发的实时性、可靠性。

With a communication middleware designed, the message receiving and retransmitting mech

确保信息收发的实时性、可靠性。IP组播信息技术在SCADA系统通信中效果良好。

Use of this software can achieve mail transceivers and management.

利用这个软件，可以实现邮件的收发和管理。

This paper provides a general study of this for transceivers with the zero-forcing constraint.

本文提供了一个一般性研究这个的收发器与迫零的制约因素。

Based on the reason above mentioned, it is very important to testing and troubleshooting RF front end of the transceivers.

基于以上原因，对射频收发模块的指标进行准确的测量是一项重要的工作。

Use udp agreement prepared by the chat program, there are two procedures can be done using transceivers.

这是使用udp协议编写的聊天程序，里面有两个程序，都可以做收发使用。

The concept of equivalent rotationally rigidity is offered and the formula of rotationally rigidity is obtained.

主要做了如下几个方面的工作：对伸臂位于顶部的单层框架—筒体模型进行分析，提出了等效转动约束的概念和转动约束刚度的表达式。

Male cats normally do not need aftercare with the exception of the night after the anesthetic.

男猫通常不需要善后除了晚上的麻醉。
