In perhaps the most ambitious project of all,Motorola plans to launch a wireless system called Iridium

在这个堪称最浩大艰巨的工程中，摩托罗拉公司计划开展一个名为"铱计划"的无线通信系统

In the chapter three, the analysis and the implement detail for all modules based on ISE 4, both transmitter and receiver unit, have been given in this section.

第三章给出了扩频通信系统的总体设计和发射及接收子系统的各个功能模块的实现分析以及在ISE 4上的实现细节。

In this paper, the jitter performance of high-speed digital serial communication based on electronic signal is investigated.

本论文主要研究的是基于电信号的高速数字串行通信系统中的时间抖动性能。

Synchronization technique which is regarded as the one of the three keystone technique of the CDMA is very important.

摘要作为码分多址的三大支撑技术之一的同步技术在CDMA扩频通信系统中是至关重要的。

In this paper, an all fluid Kraken normal model is employed to analyze the propagation characteristics of shallow water channels.

本文采用了一种全液态Kraken简正波模型，对位于浅海信道的目标海区的传播特性进行分析，得到了不同传播条件下信道的传播损失和频率特性图，为水声通信系统的设计提供了理论基础。

In this thesis, based on a simple piece-wise linear map, a chaotic FH code featuring good balance property, hamming correlation property and large FH span is developed.

众所周知，设计好的跳频码和在混沌跳频通信系统中实现收发双方的同步是很困难的。

All these have put forward higher demand to linear degree of the communication system.

这些都对通信系统的线性度提出了更高的要求。

The main works are as follows:The dissertation gives a discussion and generalization all kinds of location methods fundamental principle then compares these methods performance, realizable complexity and applied circumstance.

本文在深入研究了无线蜂窝通信系统的定位技术基础上，阐述了作者在其中几个问题上所做的工作详细讨论和总结了各种定位方法的基本原理，并且对这些方法的性能、实现复杂度和适用环境进行讨论比较。

The outstanding problem is to map abstract entities onto real entities,both effectively act on the environment,and to allow the environment to influence specification behavior.The paper describes the opportunities provided by TOPO,a compiler from LOTOS into C or Ada code.

对于通信系统的抽象说明，LOTOS语言被设计成为高级别的说明语言，它拥有强有力的多路径汇聚结构，允许用户请求的精确描述，而不是任何一个详细的执行，通过按时间排序的微小事件LO-TOS来模化实际。

The efficiency of digital communication system is advanced and the cost is lowered.

提高了数字通信系统的效率，降低了成本。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
