In this paper, we investigate a practical pilot design for indoor channels with an analysis of channel estimation for block and comb-type pilot arrangement. For the pilot design over indoor channels, the performance is determined by the tradeoff between the interpolation error by frequency selectivity of channel and the noise reduction by the interpolator, compared to the doppler effect. Results show that the performance of channel estimation for the comb-type pilot symbol with respect to the derived criterion outperforms that of the block-type pilot symbol for indoor channels, whereas it's a slow-fading environment.
