同时通信 meaning in English
simultaneous communication
Examples
- Two - way simultaneous communication
双向同时通信 - With the development of image processing and recognition technique , machine vision system has become an advanced technique . at the meantime , communication technique development give machine vision the feasibility of theory
随着图像处理技术的发展,机器视觉系统成为一门前沿技术,同时通信技术的发展为机器视觉提供了理论的可行性。 - The prevalence of modern computer and the developing of its functions have moved the single computer usage to the systematic usage . at the same time , these have given a good basis of the edi ' s moving to the internet : the perfecting of the communication and the techniques , the prevalence of the network and the appearance of the xml language
现代计算机的大量普及和应用以及功能的不断提高，已使计算机应用从单机应用走向系统应用；同时通信条件和技术的完善，网络的普及和xml语言的出现又为edi向互联网的发展提供了坚实的基础。 - Cdma has become the main technology of the third generation mobiletelecommunication . many users in cdma system are distinguished by differentspread sequences and have the same time chip and frequency unlike in theconventional tdma system or fdma system . but the practical spread sequences cannot reach the ideal condition , the correlation function equals zero , so that it will causethe multiple access interference ( mai ) when lots of people are communicating . multi - user detection ( mud ) makes joint detection on the received signals by makingfull use of the information of all users ’ , which relaxes mai and increases the capacityof system
Cdma技术已经成为第三代移动通信系统中的主流技术,它与传统的fdma 、 tdma不同,在cdma系统中多个用户均占用同一时隙、同一频隙,所不同的是选取的地址码不同,而实际选用的地址码间的互相关函数又不可能全部达到理想状态的全为零,因而造成了多个用户同时通信时,必然要产生多址干扰。 - The thesis proposes the current developing status of integrated automation in substations and the tasks of the research firstly , then introduces the comprehensive design of the system , and then focuses on the design of the communication modules both in main - station and sub - station . to improve the communication efficiency between main - station and sub - stations , the thesis brings forward a solution of multithreading in main - station . thus , the main - station can communicate with multi sub - stations at the same time and can display the states of the threads dynamically
本论文首先介绍了系统开发背景及国内外发展趋势并分析了课题意义；接着，对系统的总体设计和功能规划进行了总体介绍；然后，对主、子站通信相关模块的软件设计，从设计思想到实现上，进行了详细介绍：针对主站与子站一对一通信耗时长、资源利用率低的状况，提出了主站多线程解决方案，实现了主站与多个子站同时通信。
