AB - Finite Radon Transform (FRAT) mapper computed in Fourier basis using fast Fourier transform 
(FFT)  algorithm  has  the  ability  to  increase  orthogonality  of  sub-carriers,  it  is  non  sensitive  to  channel 
parameters  variations,  and  has  a  small  constellation  energy  compared  with  conventional  FFT  based 
orthogonal  frequency  division  multiplexing  (OFDM).  It  is  also  able  to  work  as  a  good  interleaver  which 
significantly  reduces  the  bit  error  rate  (BER)  performance  of  the  OFDM  system  under  severe  channel 
conditions. In this paper the idea is developed towards increasing the orthogonality and increasing spectral 
efficiency of OFDM system structure. FRAT computed in discrete Multiwavelet transform (DMWT) basis is 
implemented in OFDM systems and compared with FRAT OFDM computed in Fourier basis under different 
channel  conditions  for  different  channels  parameters  values  including  multi-path  gains  vector,  multi-path 
delay  time  vector,  and  maximum  Doppler  shift.  As  a  result,  the  proposed  structure  gives  a  significant 
improvement  in  BER  performance  in  Additive  White  Gaussian  Noise  (AWGN)  channels,  flat  fading 
channels (FFC), and multi-path selective fading channels (SFC).
