  Performance comparison of DWT OFDM systems and FFT OFDM system over an AWGN channel

  By Adrija Roy, Sarita Boolchandani

  Abstract: Orthogonal frequency-division multiplexing (OFDM) is a method of encoding digital data on multiple carrier frequencies. The OFDM systems till now have been used as what we can call as a conventional OFDM incorporates Inverse Fast Fourier Transform (IFFT) blocks in their transmitters and FFT (FFT) blocks in their receivers. Recent research shows that the use of Inverse Discrete Wavelet Transform (IDWT) in place of IFFT and Discrete Wavelet Transform (DWT) …
