A mobile radio communications system often experiences a considerable signal fluctuation due to time- selective fading channels. In an extremely fast fading, we cannot achieve an accurate channel estimation in general. In this paper, we derive an optimum weighting for a higher-ordered least-squares channel estimation, and prove that the zeroth-ordered scheme minimizes a channel estimation error. Furthermore, we propose an efficient weights generation method for decision-directed channel tracking. Through performance analyses, we demonstrate that the proposed scheme offers an accurate channel estimation with a reasonable computational complexity even in fast fading channels. |
