    摘要: A method and apparatus are provided where a neighbor cell interference signal is canceled upon receiving a signal transmitted from a serving base station (BS) in a receiver of an Orthogonal Frequency Division Multiple Access (OFDMA) system. The interference signals are detected from signals received from neighbor BSs and a serving BS. The strength of the detected interference signals is measures, and a determination is made whether the measured strength is higher than a threshold value. A list of neighbor BSs satisfying the determination result is reordered, and interference signals in order of the reordered neighbor BSs are selected and detected. An interference/noise variance for the detected interference signal is calculated and normalized. The normalized interference signal is decoded and regenerated, and the regenerated interference signal is subtracted from the received signal.

    摘要: An apparatus and method for estimating a carrier-to-interference-and-noise ratio (CINR) of a received signal in an orthogonal frequency division multiplexing (OFDM) system are provided. A band-pass filter attenuates a signal region of the received signal and passes a signal in a noise region. A first power calculator calculates interference and noise power of the noise-region signal received from the band-pass filter. A second power calculator calculates total received power of the received signal. A ratio calculator calculates a CINR based on the interference and noise power, and the total received power.

    摘要: A gain control apparatus of an interference cancellation receiver that performs interference cancellation in a frequency axis in an Orthogonal Frequency Division Multiple Access (OFDMA) system. A first signal power measurer measures first signal power of a received signal that was received from a base station and then underwent fast Fourier transform (FFT). A first range controller generates a first range control value for matching the first signal power to an operating point of the FFT-processed original signal. An FFT output buffer buffers the FFT-processed received signal. A second signal power measurer measures second signal power of a regenerated interference signal. A second range controller compares the first signal power with the second signal power, and generates a second range control value for controlling a gain of an output signal according to an operating point of a signal obtained by canceling the interference signal from the received signal output from the FFT output buffer.

    摘要: An apparatus and method for estimating and reporting a Carrier to Interference Noise Ratio (CINR) in a wireless communication system are provided. The wireless communication system receives the CINR reported from the mobile station and transmits data by adaptively setting a coding and modulation level. In a mobile station, a Radio Frequency (RF) processor provided with at least two antennas processes antenna-by-antenna radio signals and converts the radio signals to baseband signals. Switches output or intercept the antenna-by-antenna signals received from the RF processor. An effective CINR measurer measures diversity parameters including a CINR value from the signals output by the switches and outputs the measured diversity parameters. A controller controls an operation for turning on/off the switches on a basis of the diversity parameters received from the effective CINR measurer and generates a report message using the diversity parameters. A transmitter transmits the report message to a base station.
