A 3780-point FFT algorithm and its FPGA implementation

  title={A 3780-point FFT algorithm and its FPGA implementation},
  author={Gang Cheng and Kai-xiong Su},
  journal={2010 International Symposium on Next Generation Electronics},
In this paper, a 3780-point FFT algorithm combining of Good-Thomas, Cooley-Tukey, and WFTA algorithm is presented and its hardware implementation by using shift rules based on the analysis of the finite word length effect is described. The simulation results show that the output SNR meets the requirement of TDS-OFDM system.
