Abstract
Official abstract text for this publication.
Disclosed are an apparatus and a method for normally receiving data by accurately estimating and compensating for a frequency offset for a wireless frequency channel through which data are transmitted in a communication system under wireless frequency environment. In the present invention, data transmitted through the wireless frequency channel are received, the frequency offset in the wireless frequency channel from the receive data is estimated based on an interpolation scheme using the periodogram, and the frequency offset is compensated to receive the data by frequency-synchronizing with the wireless frequency channel.
First claim
Opening claim text (preview).
What is claimed is: 1. An apparatus for receiving data in a communication system, comprising: a receiving unit configured to receive data transmitted through a wireless frequency channel; an estimating unit configured to estimate a frequency offset in the wireless frequency channel from the received data, based on an interpolation scheme a periodogram, wherein the estimating unit estimates a real frequency offset generated at the time of transmitting and receiving data based on…
