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

摘要

Using a power spectrum for a pilot channel symbol estimate the speed of the moving object, and there is a demodulation method and a demodulator of a mobile communication terminal for performing channel estimation and channel compensation by using this are disclosed. Demodulator of the mobile communication terminal comprises thee Explorer, channel estimators, channel compensator and combiners. A channel estimator for using the power spectrum of the pilot symbol channel estimates the speed of the moving object, and the channel estimate to reflect this. A channel compensator for channel compensation by using the estimation result of the channel estimator. Thus, the moving object may be in a high-speed wireless channel environment moving at high speed to improve the reception performance of the receiver.
