- direct down conversion 直接下变频
- The radar digitalized receiver is based on Digital Down Conversion (DDC) technology, which is implemented on FPGA. 雷达数字化接收机部分是基于数字下变频(DDC)技术在FPGA上实现的算法研究及工程实现;
- The common approach to implement DDC (Digital Down Conversion) on FPGA is based on a look-up table, which requires a huge volume of ROM to achieve high resolution. 摘要数字下变频的FPGA实现通常都是基于查表的方法,为了达到高精度要求,常常需要耗费大量的ROM资源去建立庞大的查找表。
- Moreover, this paper explores how to make use of DSP, CPLD, Digital down conversion (DDC) device, ect, to construct a SDR IF receiver which can carry out the demodulation function of AM signal if AM demodulationprogram is downloaded. 利用DSP、CPLD、数字下变频器等器件,构造了一个软件无线电中频接收系统,对该系统下载AM解调程序,它可以执行AM信号的解调功能。
