Design of Parallel FFT Based on FPGA in the Field of Software Radio

摘要：

　　Most of the high-speed signal processing functions in software radio are used to realize the transformation between time domain and frequency domain by Discrete Fourier Transform(DFT)first.However the time consuming in calculation of DFT is too large to apply in practice so that Fast Fourier Transform(FFT)is proposed.In this work,we develop a design of parallel FFT in which the data exported by every butterfly processing element flow to the next level directly without storage in order to avoid data stack.The method of data truncation is to obtain the high 16 bits of the data exported by every multiplier and to halve the calculation results of butterfly elements at each level.
