The use of the efficient 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 one dimensional interpolation is presented. The proposed interpolation technique...
Orthogonal Frequency Division Multiplexing (OFDM) is a spectrally efficient and robust digital communication technique adopted by the newly developed Wireless Communication standards. Frequency offset errors due to Doppler shifts disturbs the alignment of the orthogonal subcarriers and causes them to overlap with each other which results in Inter Carrier Interference (ICI). This paper proposes the...
Channel Estimation in Orthogonal Frequency Division Multiplexing (OFDM) is imperative for cancellation of the impairments introduced by the fading channel. In this paper, the performance of Least Square (LS) estimator is studied for comb-type and block-type pilot insertion schemes over fast and slow fading Rayleigh channels respectively. The channel order increases proportionally with the distortions...
