It is considered the most promising way to resolve the problems . after several years " investigation , it is convinced that not only wireless modems should be implemented via software , but also the architecture of wireless systems should be reconstructed 软件无线电思想经过几年的发展，目前研究者认为，不仅要对调制解调进行数字化、软件化处理，还需要从系统的角度来重新构建整个无线通信系统。
As increasing numbers of broadband users gather in crowded spaces such as airports , hotels , convention centers and workplaces , the most critical parameter of a wireless system will be its spatial capacity , a capability in which uwb technology excels 随著愈来愈多的宽频用户聚集在拥挤空间，像是机场、饭店、会议中心与办公室，无线系统最关键的一项参数将是空间容量，而超宽频技术在这项能力上的表现独占鳌头。
Because the system includes some wireless terminals and a server , in order to implement one to many communication of the whole wireless system we design wireless communication protocol . the protocol consists of physics layer , link layer and application layer 由于整个系统由多个无线终端和一个服务器组成，为完成整个无线通信系统的一对多通信，文中设计了一个无线通信协议，该协议由物理层、链路层与应用层组成。
Then from the point of system design and development , it gives an specific analysis of bluetooth wireless system feasibility , proposes a dedicated management protocol stack architecture on the basis of software project theory . at last , a suggestion implementation is introduced 在第一部分的基础上，从系统实现的角度对系统的架构进行解析，提出专用系统架构设计方案，详细分析各层的功能与实现，并给出参考实现的详细设计。
The emergence of multiple - input multiple - output ( mimo ) technology meets the demand of multimedia applications and high speed wireless access . researches indicate that the mimo can improve the performance of wireless system prominently , such as system capacity , data rate , and frequency efficiency 为了满足未来移动通信系统大容量、高速率的需求，提高频谱利用率，学术界提出了多天线发送和多天线接收的多输入多输出( mimo )系统的概念。
Not just through wireless systems of our internet age , but between god almighty , and between jesus christ and the human family . and then between human beings into whose brain god is sending messages , answering prayers and inspiring people with the presence of jesus christ 我们对那儿一无所知，但这并不重要，我们只知道有属灵的宇宙，在这宇宙内充满了隐藏沉默和触摸不著的信息往来，这些信息不单透过网络时代的无线系统往来，这些信息来往于全能的神耶稣基督和人们的脑海中。
In the net , there are some buses or wireless systems to connect sensors , processors ( for control policies ) and executors , and computer networks for information ( especially useful in community intelligence and remote control ) , they are the basis . the kernel of smart is the terminal , a control system which is used to process the control policies , and give a friendly interface to users 在这个网络中有负责传感器、控制策略处理器、执行器之间通信的各种总线系统或者无线系统;也有负责信息交换的计算机网络系统(在实现园区智能和远程控制方面更能充分发挥其优势) ,但智能的核心还是负责控制策略执行的控制系统,也即嵌入式智能家居控制终端。
Motivated by the increasing demand of the modern society for high - speed reliable information exchanges anytime and anywhere , broadband wireless systems ( bws ) are envisioned for future mobile communication networks . it has been widely acknowledged that the terrestrial bws faces a formidable challenge due to the frequency - selective multipath fading propagation environment 随着现代社会对个人通信要求的不断提高,人们要求实现任何人在任何时间、任何地点与任何人进行任何种类的信息高速可靠交换,宽带无线系统( bws )非常适合个人通信发展的要求。
In this device msp430 was selected as cpu to complete the task of sampling , processing and saving data . the backstage computer in the monitoring room communicates with each field device by wireless system . the computer receives and processes the data from field on time in order to predict alarm or give an alarm on the insulators contamination and humidity state 此外系统还采用msp430单片机作为cpu来完成数据的采集、处理和存储等功能，由监控室内的后台机对现场抄收的数据进行处理、判断，对各个绝缘子的污湿状态进行预警或报警。
The system has a good security and can prevent the pervasion of mistake code , has a well anti - jamming ability and so on . some substantial and groping work has been done in the process of using chaos security communication in pulse wireless system and the multi - access communication of chaotic pulse position modulation 系统具有很高的保密性，具有防误码扩散，抗干扰能力强等特点，同时也为混沌保密通信应用于脉冲无线电系统以及混沌脉冲位置调制的多址通信方面做了一些实质性和探索性的工作。
