    摘要: A Signal-to-interference ratio (SIR) measuring apparatus in a multiple antenna high data rate packet transmission system measures signal energy to interference energy ratio by using pilot signals that are orthogonal to each other between antennas signals and used by a receiver for separating the signals transmitted from all of the transmitting antennas from each other. The SIR measuring apparatus comprises a signal energy measuring unit, an interference energy measuring unit and a SIR measuring unit. The signal energy measuring unit measures signal energy by synthesizing after coherently integrating and non-coherently integrating values that are obtained by correlating a received signal with pilot patterns equal to the pilot patterns of transmitted antenna signals, respectively. The interference energy measuring unit measures interference energy by coherently integrating and non-coherently integrating after correlating the received signal with another pattern that is orthogonal to the pilot patterns of the transmitted antenna signals but is not transmitted. The SIR measuring unit measures SIR by using the measured signal energy and the measured interference energy.

    摘要: The present invention relates to a method for detecting a signal in an MIMO system. In the method, a received signal is detected in a zero forcing (ZF) method, and a first detection interval is established from the signal detected in the ZF method. The received signal is detected within the first detection interval in a maximum likelihood (ML) method, a second detection interval is established from the signals respectively detected in the ZF method and the ML method. A final solution is determined by detecting the received signal within the second detection interval in the ML method.

    摘要: Disclosed is a forward channel configuring method in an OFDMA FDD system. The method comprises: classifying the cells into a specific number of patterns based on location relations of the respective cells; allowing the respective base stations of the cells having different classified patterns to transmit control information to the mobile station at different times within a period of the forward channel, and allowing the respective base stations of the cells having the same classified patterns to transmit control information to the mobile station at the same time; and allowing the respective base stations to transmit traffic data to the mobile station irrespective of the classified patterns when the control information is transmitted.
