Abstract
Methods and apparatuses are provided for driving a modem. A Channel Impulse Response (CIR) is computed through channel estimation. An estimation time position is estimated by applying a weighted-average method to the CIR. A time offset is measured by comparing the estimation time position with a reference time position. The time offset is compensated for.
