软件定义 meaning in Chinese
software definition
Examples
- Software testing plays a more and more important role in the software development and it performs its functions during the whole period of developing
软件测试在软件开发过程中有着越来越重要的地位。它贯穿于软件定义与开发的整个期间即整个软件开发过程。 - After the evolution from analog to digital , and from fixed to mobile communication , radio systems are undergoing the third revolution from hard - wired radios to software - defined radios
软件无线电是无线电领域模拟通信到数字通信，固定通信到移动通信之后，从硬件定义的无线电通信到软件定义的无线电通信的第三次革命。 - Due to the hardware characteristic ' s limitation , such as the poor speed of a / d , d / a conversion and dsp process , the most part of sr system adopt middle course . that is to say , by using the special digital converter or running relevant arithmetic , it converts the radio signal to intermediate frequency signal and completes the base - band signal process that is n ' t the veriest sr and is named " software defined radio ( sdr ) "
由于受到硬件性能如a d 、 d a及dsp芯片处理速度的限制，目前的软件无线电系统多采用折中的实现方案，增加专用的数字变频器或者运行数字变频算法，将射频信号变频到中频，然后再进行基带信号处理，这样的软件无线电系统又被称之为“软件定义无线电” ，它并不是真正意义上的软件无线电。 - Software - defined radio ( sdr ) defines radio communication functions using software on a general , open hardware platform that possesses scalability itself , which not only relieves communication systems from the constraints of hardware elements but also enables seamless connection between kinds of wireless communication systems and supports flexible services
软件无线电在通用的、开放的硬件平台上通过软件定义无线通信功能，而且硬件平台本身也是可扩展可升级的，这就使得通信系统摆脱了硬件的束缚，可以实现各种通信体制的无缝连接，提供灵活多变的服务。 - Software defined radio ( sdr ) has been the trend of the research and development of radio , and its core idea is to provide a software system which can enable reuse and reprogram of common blocks on an universal hardware platform , so as to deal with the traditional inconsistent communication systems and solve the cooperating communication problems
软件定义无线电台( sdr )已成为当今及未来无线电系统研究及发展的方向,其核心思想是在通用的硬件平台上,提供一种具有组件可重用,可重编程等功能的软件系统,解决传统通信系统体制不统一,协同通信能力差的问题。
