In this letter, we investigate an analysis of channel estimation using an interpolation technique in orthogonal frequency division multiplexing systems. Then a criterion for the adaptive interval of pilot subcarriers is derived. The mean-square error (mse) of comb-type estimators is dominated by the length of channel delay and the interval of pilot subcarriers. Analysis shows that the mse performance of comb-type estimators with the adequate interval of pilot subcarriers is better than that of block-type estimator for indoor channels.
