A 3780-point FFT algorithm and its FPGA implementation
Gang Cheng, Kaixiong Su · 2010
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.
