Abstract :
This paper presents an iterative inter-carrier interference (ICI) cancellation method using compressed sensing (CS) based channel estimation. Simulation results demonstrate that the proposed method can significantly improve the bit error rate (BER) performance for Orthogonal Frequency Division Multiplexing (OFDM) systems in comparison with the conventional Least Square (LS) based methods.
