Abstract
In modem communications the FFT/IFFT has been normally used in recent years due to its effectiveness in OFDM applications. In this paper multiplierless radix-2/4 FFT architecture using MBSLS was proposed, but here constant multiplication is replaced by shift and add structure unit. The memory of the twiddle factor is minimized by increasing the computation speed with the help of Winograd Fourier transform algorithm. Thus the proposed method offers minimal hardware requirement as well as reduction in complex multiplication in FFT calculation. This method achieves good performance in terms of less area. This architecture has been simulated in Xilinx ISE12.14 software by using Verilog coding and is used in the mobile Wi-MAX application in OFDM.
