| 摘要 |
The present invention is related to a method and apparatus for estimating Doppler speed in wireless communication. The apparatus comprises a receiver, a sampler, a pilot/data removal unit, a phase change rate (PCR) measurement unit, a Doppler speed value calculating unit. The receiver receives signals, and the sampler samples the received signals. The pilot/data removal unit removes pilot or data information from the samples. The PCR measurement unit measures a PCR of the samples and the Doppler speed value calculating unit calculates a Doppler speed value based on the PCR. The Doppler speed value calculating unit is preferably a look-up table or a mapping functional unit.
