Patent ID: 8102952

Claim:
A method for controlling interference in an Ultra-Wideband (UWB) wireless communication system of a multi-user environment, the method comprising: receiving, by a pulse receiver coupled to an antenna, a plurality of signal pulses that are each transmitted a number of times; calculating a first correlation value by applying a correlation mask to a first signal pulse; determining a threshold value by referring to the number of times that the first signal pulse is transmitted, a signal-to-interference-and-noise ratio (SINR), and information about a ratio of a near-interference to a far-interference; and eliminating the first signal pulse when the first correlation value is greater than the threshold value, wherein the determining a threshold value comprises: estimating an expected correlation value for a normally received signal pulse; calculating the SINR based on the expected correlation value; calculating a ratio of distorted signal pulses from among the plurality of signal pulses by referring to correlation values calculated for each signal pulse of the plurality of signal pulses, the expected correlation value, and the SINR, the distorted signal pulses having a waveform distorted by the near-interference; and calculating the threshold value by referring to the ratio of distorted signal pulses.
