| 摘 要： | 数字单边带下变频器是软件无线电中不可缺少的组成部分,也是射电观测中,数据采集设备的重要组成部分,由于该模块紧接高速A/D采样器之后,所以对其运算处理能力有很高的要求.本文提出了实现宽带数字单边带下变频器的一种可行方案——并行处理,可以从根本上解决数字信号处理的瓶颈效应.

| Abstract: | Digital single side band(SSB) down converter is an important part in software radio receiver as well as in data acquisition terminal of radio astronomy.Because the down converter follows the high speed Analog-Digital sampler directly,the requirement on the capability of processing data is very strict.In this paper,a parallel architecture is presented to implement Wideband digital SSB down converter,which can solve the DSP 'bottle-neck'. |
