    摘要: A method for measuring channel quality of a Base Station (BS) by using a ranging signal in a broadband wireless communication system is provided. The method includes estimating a time offset of the ranging signal received through a ranging channel, measuring channel quality by using the ranging signal including the time offset, determining whether distortion occurs in the measured channel quality by using the time offset, and compensating for distortion of the measured channel quality.

    摘要: An apparatus and method for eliminating interference in a base station (BS) of a communication system. A first BS receives a first reception signal from a first mobile station located in a cell of the first base station. A second base station being adjacent to the first base station delivers decoding information of a second reception signal to the first base station, the second reception signal received from a second mobile station located in a cell of the second base station. The first BS determines whether an error exists on the second reception signal, based on the decoding information and re-generates an interference signal using the decoding information of the second reception signal when no error exists in the second reception signal, and performing interference elimination on the first reception signal using the re-generated interference signal.
