摘要：
An apparatus and method for intercell interference cancellation in an OFDMA broadband wireless access communication system is provided. The method includes deriving a first channel estimate value of a desired signal and a first interference channel estimate value of an interference signal by using burst allocation information of selected sectors or cells; deriving a first noise estimate value using the first channel estimate values and the first interference channel estimate value; detecting an interference signal interfering the desired signal by using the first interference channel estimate value and the noise estimate value; deriving burst allocation information of the detected interference signal and the desired signal; and deriving a second channel estimate value of the desired signal and a second interference channel estimate value of the interference signal using the derived burst allocation information.
