Implementation of STFT based on FPGA

For its short processing time and easy implementation,STFTC(Short Time Fourier Transform) is increasingly applied in the image processing and signal detection.Based on analysis of STFT,a new FPGA-based rapid STFT implementation architecture is proposed and designed.By fully utilizing the operational property of Butterfly processing element,this architecture could reduce the computation complexity on the basis of satisfying frequency and time resolution,and thus save the hardware resource in high-speed operating clock.
