In this paper, effect of packet duration and channel prediction is analyzed in adaptive modulation. Spectral efficiency equations are derived for both systems with and without channel prediction. Numerical results show that systems with channel prediction can get maximum spectral efficiency while systems without channel prediction but chosen optimum packet duration can get suboptimum spectral efficiency, which is inversely proportional to Doppler frequency.
