摘要： An Ultra-Wideband (UWB) wireless communication system in a multi-user environment determines a threshold value to eliminate a signal pulse affected by a near-interference from among a plurality of signal pulses transmitted a number of times. A method for controlling an interference includes receiving the signal pulses, calculating a correlation value by applying a predetermined correlation mask to the signal pulses, determining a threshold value by referring to the number of times that the signal pulses are transmitted, a signal-to-interference-and-noise ratio, and information about a ratio of a near-interference to a far-interference, and eliminating signal pulses having a correlation value greater than the threshold value. The correlation values that are not greater than the threshold value are summed to detect a bit corresponding to each pulse signal.
