Abstract .The demand for high-speed wireless communications is rapidly growing, in this paper a new technique is proposed to improve the performance of OFDM. The new technique is use the Parallel 2D FFT algorithm instead Fast Fourier transform (FFT) in order to reduce the level of interference in the flat and selective fading channels, where the improvement was 3-4 dBs.
Keywords : FFT, 2D FFT, OFDM
