通信系统

In this paper we will discuss the problems of information processing, processing mode and circuits relevant to such processing for a newcommunication system--the time division multiplexing communicationsystem with defence time

本文介绍一种新的通信系统——时分保护制通信系统的信息处理问题，处理方式问题及与处理有关的电路问题。

The results are the information transmission capacity of communications essentially lies on information carrier and information transmission mode,and on nowadays communication modes the information carries only by use of the space degree of freedom of signals and the information transmits only by use of the undulatory property of signals.

研究结果表明，通信系统的信息传输能力由信号承载和传输信息的方式决定；现有电子通信系统中信号处于低速宏观态，仅利用空间自由度承载信息和波动性传输信息，香农公式定量描述了该状态中信号的信息输运能力；高速态、微观态或介观态信号的信息输运能力有可能突破香农公式限制。

Echo canceller is widely used in PSTN system, mobile communication system, video teleconferencing system, and other speech telecommunication fields.

回波消除器广泛应用于公用电话交换网、移动通信系统和视频电话会议系统等多种语音通信领域。

Communication system and the network construction must be suported by the designer , constructer and project manager.

通信系统和通信网络的建设离不开通信工程设计、施工和监理。

Convolutional coding has been used in communication systems including deep space communications and wireless communications.

中文摘要：卷积编码是深度空间通信系统和无线通信系统中常用的一种编码方式。

Its basic idea is to realize all kinds of radio communication functions, such as work band, kinds of modulation or demodulation, data format, encrypt mode and communication protocol by upgradable and displaceable software on a hardware platform which is opening, expanded and simple structure. And it makes wideband A/D and D/A converters close to the antenna, in order to develop more flexible and opening wireless communication system.

它的基本思想是以开放的、可扩展的、结构最简的硬件为通用平台，把尽可能多的通信功能，如工作频段、调制解调类型、数据格式、加密模式、通信协议等用可升级、可替换的软件来完成，并使宽带A/D和D/A转换器尽可能地靠近天线，以研制出具有高度灵活性、开放性的新一代无线通信系统。

On the chaos correspondence question, this article proposed the implicational method of chaos system in the secure communication system.

就混沌通信问题，本文提出了有关混沌系统在保密通信系统的实现方法。

Job experts who communicate by letter throw this feasible whole world more distant with sight having faced fourth communicating by letter on behalf of displacement, to look forward to on behalf of moving an insolvable problem coming to resolve 3 G communication system by fourth, the nothing crack realizing the wireless network of commerce , local area network , blue-tooth , radio and television, satcom ultimately is link up and mutually compatible, realize "anybody fond dream switching in a network with any form in any place" really.

这使得全世界通信业的专家们将目光更远地投向了第四代移动通信，以期通过第四代移动通信系统来解决3G无法解决的问题，最终实现商业无线网络、局域网、蓝牙、广播、电视卫星通信的无缝衔接并相互兼容，真正实现&任何人在任何地点以任何形式接入网络&的梦想。

The B3G mobile communication system interworks several communication technologies, which will realize people's dream of"always best connected".

未来的后3G(B3G)移动通信系统是不同通信技术的融合，实现了人们总能享受最佳通信服务的愿望。

It is essential for a practic al communication system to provide the services with adequately low interruption probability.

摘 要：基于提供一个足够低的通信中断概率是任何一个实用通信系统所必具的性能，提出了一个简略的平流层蜂窝通信模型。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
