摘要
软件无线电技术在商用和军用无线电通信领域越来越显示出其强大的吸引力,而ADC是软件无线电的关键技术。概括了A/D转换器在无线电接收机中的应用,分析了其动态性能中互调失真、SFDR(无杂散动态范围)、孔径抖动对接收机性能的影响。最后以AD公司的AD9445为例,进行了仿真。
The technology of software radio plays an important part in the commercial and military radio communication. Its key technology is ADC.This paper introduces the implication of ADC in the software radio receiver,analyses its dynamic performance including harmonic distortion, SFDR, aperture jitter and their influence on the performance of the receiver. At last, the paper takes the AD9445 as the example to simulate their performance.
