基站

Noise is measured at one or more base stations in a mobile communication system during periodic silence periods.

在周期性无声期期间在移动通信系统中的一个或更多基站上测量噪声。

Many domestic and foreign companies and universities are making research on the architecture and system of RF power amplifier.

本文所讨论的射频预失真放大系统的设计正是为更好的实现射频大功率放大器的线性化而进行研制和开发，特别是针对WCDMA基站中的应用。

The methods described provide for the transmission power of the base stations (4, 6) to be aligned.

所描述的各种方法使基站(4，6)的发射功率得到调整。

A novel regulated AC power supply unit for base stations using double PWM is presented in this paper. The main circuit and its principle of operation are introduced, and the power flow analyzed.

提出一种新的基于双PWM技术的新型通信基站稳压电源的拓扑结构，并对这种拓扑结构的主电路和工作原理进行了介绍，对其功率流进行了分析。

The base station is a bit pricy —$180 — but I think it's worth every penny.

基站是一个位pricy -1 80元-但我认为值得一提的每一分钱。

At the transmitter, the precoder is constructed as the function of all users'channel state information according to the performance criterion of minimizing average probability of vector symbol error.

在基站发射端，根据最小平均矢量符号错误概率准则，预编码器构造为所有用户信道状态信息的函数。

A proper determination of the frequency plan.

择基站位置和适当确定频率规划方案提供很好的基础。

The research and development of visualization system of electromagnetic environment monitor is very necessary, and it is very important significance. It can assure the quality of communication for avoiding the interface of electromagnetic signal, live up to reasonable layout and distribution for the construct of mobile communication station and radio monitor station, reduce the endangerment electromagnetic radicalization for surrounding environment and body of people.

为了避免电磁信号之间的相互干扰，保证通信的质量；为了对移动通信基站或无线电监测站的建设，做到合理的规划和布局；为了减少电磁辐射对周围环境和人体的危害，研究并开发电磁环境监测可视化系统就显得很有必要，具有十分重要的意义。

In more technical language, a "brick" is a station in the mobile service consisting of a hand-held radiotelephone unit licensed under a site authorization.

在更多的技术语言中，"砖头"是移动业务中的一种工作站，包括经过基站鉴权批准的手持式对讲机。

The system can obtain the real-time image of the monitored scene. By image detection of the moving object, the wireless image transmission device can give off alarm signals when moving objects enter the scene. Then alarm signals and real-time image are transmitted through wireless receival station into the monitoring room for inspection.

该系统可以获取被监控现场的实时图像，对图像中运动物体检测，当有运动物体进入监视现场时，无线图像发射装置给出报警信号，并将报警信号以及实时的图像画面通过无线图像发射装置发射出去，通过无线接收基站传入监控机房，监控人员可以在监视器上观察报警现场的情况。

In the United States, chronic alcoholism and hepatitis C are the most common ones.

在美国，慢性酒精中毒，肝炎是最常见的。
