Abstract


Orthogonal Frequency division multiplexing is a popular method for high data rate applications and is corrupted by impulsive noise. Methods must be investigated to mitigate this noise. In this paper, a State Space Recursive Least Square (SSRLS) algorithm based adaptive impulsive noise suppressor ofdm communication is proposed. It gives the better tracking due to its state space model-dependent recursive parameters. The proposed method came out to be very effective in noise cancellation of OFDM signal without requiring reference noise source. The fastest convergence and better tracking characteristics of proposed scheme demonstrated by the simulation results in mean square error (MSE) sense proved to be the effective solution for the impulsive noise cancellation in OFDM signal.
