ANN assisted Turbo coding for use with OFDM signals in wireless channels

This paper deals with adding ANN assisted Turbo coding and decoding to OFDM signal for transmission in the wireless channel. Channel coding improves the performance of OFDM signal, but the system design becomes complex due to the iterative decoding technique. The system design can be simplified and made faster by the use of ANN in the coding and decoding process. Simulation is done in MATLAB to analyse the BER performance of Turbo coded OFDM in Rayleigh and Rician fading channel.
