  • Apparatus for measuring signal-to-interference ration in multiple antenna high data rate packet transmission system and method thereof
    Patent number: 7145935
    Abstract: 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.
