摘要
宽带数字化接收机是当前无线通信领域的一个研究热点,高速模拟/数字转换器ADC又是实现数字化接收机的核心部件。首先简述了宽带数字接收机与传统窄带数字接收机结构上的差别,然后着重研究了ADC对接收机性能的影响。最后还列举了AD9042芯片在宽带数字接收机中的设计与应用。
The digital wideband receiver is a research hotspots in the current radio communications field and an analog/digital converter(ADC) is the key component of implementing digital receiver.This paper introduces the structural difference between the digital wideband receiver and the conventional digital narrowband receiver and then studies the effect of ADC on the performance of the receiver. Finally,the design and application of AD9042 chip in the digital wideband receiver are shown by giving a example.
