2D Interpolation technique for Channel Estimation in OFDM Systems
Abstract: The use of interpolation technique with low estimation error is imperative for estimating the channel impulse response at data subcarriers for pilot assisted channel estimation techniques in the Orthogonal Frequency Division Multiplexing (OFDM) systems. In this paper, a novel interpolation technique based on 2 d interpolation is presented. The proposed interpolation technique is based on minimizing the interpolation error and channel noise inherent in Least Square (LS) estimation. A comparative …
