In this paper, we investigate pilot symbol assisted channel estimation in OFDM system. To obtain the consistent estimation of communication channel, it is necessary to perform filtration or interpolation on pilot symbols scattered in an OFDM frame. Different interpolation techniques on pilot symbols are investigated in this paper, concretely linear interpolation, Spline Interpolation, Cubic interpolation, Bezier curve interpolation and Lagrange barycentric interpolation. The performance of studied methods is then evaluated and compared by measuring the bit error rate (BER), mean squared error (MSE), mean absolute error (MAE) and root mean square error (RMSE) in frequency selective multipath Rayleigh fading channel. Results are then compared with perfect channel state information.
