摘　　要：基于信号分离技术在当前环境下被广泛应用的背景,该文提出了一种基于FPGA平台的信号分离系统。通过对需要分离的信号进行ADC采集,并通过FFT算法处理获取信号的频谱,从而得到叠加信号的特征。依据叠加信号的特征利用直接数字频率生成(DDS)技术生成各个叠加信号,实现对待分离信号中叠加信号的分离。该设计具有采样精度高、分离信号输出同步性好等优点,能够精确实现对信号的分离。The paper proposes a signal separation system based on FPGA platform,taking into account the widespread use of signal separation technology in the current environment.The signals to be separated are acquired through ADC and their spectrum is obtained using FFT algorithm to extract their features.Based on the characteristics of the superimposed signals,each superposition signal is generated using DDS technology to achieve accurate signal separation with high sampling precision and synchronized output.
