Apparatus and method for estimating CINR in an OFDM communication system

摘要

A method and an apparatus are provided for estimating a carrier-to-interference and noise ratio (CINR) in an orthogonal frequency division multiplexing (OFDM) communication system. The apparatus and method include a receiver for receiving a signal carried by a transmission sub-carrier including a guard band allocated to a region. Further, an estimator is provided for removing a signal component dispersed by the guard band included in a noise component of the received signal, and for estimating a CINR by calculating signal component power and interference and noise component power from the received signal from which the dispersed signal component is removed.
