Link adaptation system using doppler frequency and method using the same

The link adaptation (link adaptation) system using the Doppler frequency is disclosed. A link adaptation system Doppler (Doppler) (Signal to Noise Ratio) SNR for signals transmitted through Doppler frequency estimation, the radio channel on the basis of the estimate the Doppler frequency for estimating the frequency of a signal transmitted over a wireless channel measured taken into account the distance (interval) SNR measurement interval determiner and the determined SNR measurement interval for determining the to and including a SNR measurement for measuring the SNR of the signal. Doppler frequency, link adaptation, signal-to-noise ratio, MCS level
