Abstract
In this paper, performance comparison of FFT algorithms for OFDM system is shown and advantage of proposed SRFFT is verified through implementation. For the single input and output structure in the most OFDM communication systems, adaptation of SRFFT might be inefficient. In this paper, improved SRFFT with pipeline structured FFT/IFFT of single input and output is developed and verified with Matlab, VHDL, synthesis tool and simulation tool.
