Zheng Ji-gang · Shipboard Electronic Countermeasure · 2007
This paper introduces the application of discrete Fourier transform(DFT) and fast Fourier transform(FFT)in digital channelized receiver,and tests the core of FFT supplied by ALTERA Inc,analyses the superiority of DFT compared to the FFT in the application of wideband digital receiver,puts forward an adding-zero and glide algorithm to carry on the overlap processe to data.This algorithm is helpful to design the real-time processing digital channelized receiver.
