APPARATUS AND METHOD FOR ESTIMATING CARRIER FREQUENCY OFFSET IN COMMUNICATION TERMINAL, AND COMMUNICATION TERMINAL FOR PERFORMING THE METHOD |
摘要 |
<p>Provided are an apparatus and method for estimating carrier frequency offset in a communication terminal operating in a communication system supporting Orthogonal Frequency Division Multiplexing (OFDM) or Orthogonal Frequency Division Multiplexing Access (OFDMA). More particularly, provided are a method of estimating carrier frequency offset in a communication terminal supporting DownLink (DL) Full Usage of SubChannel (FUSC) and DL Band-Adaptive Modulation and Coding (AMC) channel modes in a wireless communication system based on one of Institute of Electrical and Electronic Engineers (IEEE) 802.16d/e, Wireless Broadband (WiBro), and Worldwide interoperability for Microwave Access (WiMAX) standards, and a communication terminal performing the method. The apparatus includes: a phase difference calculator for calculating a phase difference between pilot symbols having the same linear phase among the pilot symbols of a received signal; a phase difference accumulator for accumulating the phase difference and generating a phase difference accumulation value; and a calculator for converting the phase difference accumulation value into a carrier frequency offset estimation value.</p> |
