METHOD FOR ESTIMATING WIRELESS LINK OF A TERMINAL IN MULTI-CARRIER SYSTEM

摘要

PURPOSE: A wireless link estimation method of a terminal in a multi carrier wave system is provided to improve the reception performance of a terminal by estimating the accuracy of wireless link quality. CONSTITUTION: A subcarrier automatic co-relator(210) performs automatic co-relation between adjacent pilot subcarriers. A phase calculator(240) and a timing offset estimator(250) performs time synchronization estimation. A phase compensator(280) and an IDFT(Inverse Discrete Fourier Transform)(290) perform delay profile estimation.
