Velocity estimation apparatus and method |
摘要 |
<p>A velocity estimation apparatus and method for a communication system including a transmitter for transmitting signals through wireless channels and a receiver for receiving the signals and restoring data. The apparatus includes a pilot signal detector for detecting a pilot signal from a received signal, a maximum Doppler frequency estimator for estimating a maximum Doppler frequency using the pilot signal detected by the pilot signal detector, and an adaptive type band-limit filter having a limit band based on a previous output value of the maximum Doppler frequency estimator. By using the pilot signal, which is removed with noise, while passing through the band-limit filter, it is possible to precisely estimate a maximum Doppler frequency, and thereby estimate the velocity.
