Abstract :
This paper proposes a new approach to reduce the PAPR with a new adaptive soft feedback stochastic Hopfield neural network (S-HNN). By adopting new neural output function and random state disturbance, the PAPR performance is improved greatly. Furthermore, it can be implemented easily compared to the traditional HNN method. By parameter adjustment, the lowest PAPR can be found. So it is an effective and practical algorithm for OFDM system
