例句与用法
- The research on the background signal simulator is based on the idea of the soft wireless
背景信号模拟器的研究参考了软件无线电的思想。 - This paper introduces some practicable ways to realize the design of background signal simulator console software , database exploitation and the data processing for the gps receiver ( gn - 79 ) . to meet the needs of these superiorities such as simple maneuverability , modularization and high secrete security , we considerably think of those requirements in the aspects of the signal - producing , hardware - setting , timing and orientation , user setting and so on , during the period when we design the software , make the database accessing down to the bottom layer , and obligate full space for its improvements of software modification and function expansion
由于工程的操控部分即软件实现部分需要体现简便、易控、模块化以及保密性好等优势，因此，在设计实现操控界面的同时，充分考虑了信号产生、硬件设置、定时定位以及用户设置等各方面的要求，实现了数据库访问技术到底层的管理，为将来的软件修改、功能扩容留下了充分的空间。 - His idea is based on the fact that the pivot of the soft wireless structure is to put the broad band a / d and d / a conversion near to antenna by all means , and to define the functions of the transmitter - receiver as many as possible in the forms of software ( namely realized by software ) . the technology of background signal simulator puts the focus on the methods used to realize the software , namely to exploit the functions of the hardware ( for example , dsp fpga or asic ) through the idea of software design , and to produce ( realize ) wireless signals by high speed lsi and software programming
1992年5月的全美电信系统年会上， mitre公司的资深科学家joemitola首次给出了软件无线电的定义，他认为：软件无线电的组成架构的中心点是将宽带模?数( a d )和数?模( d a )转换器尽可能地靠近天线，将尽可能多的电台功能以软件的形式定义(即用软件来实现) 。背景信号模拟器所采用的技术集中体现在软件无线电技术，即用软件化设计去开发硬件(如dsp 、 fpga 、 asic )功能，采用高速大规模数字集成电路、软件编程的方法产生(实现)各种无线电信号。
