VELOCITY ESTIMATION-BASED CHANNEL ESTIMATION METHOD AND MOBILE TELECOMMUNICATION DEMODULATOR USING THE SAME

摘要

A channel estimator, demodulator, speed estimator and method thereof. The speed estimator may generate a speed indicator indicating a speed of a mobile device. The channel estimator may perform channel estimation based on the estimated speed indicated by the speed indicator. The demodulator may perform channel compensation based on the channel estimation performed by the channel estimator.
