Method for interference control by an ultra-wideband wireless communication system in a multi-user environment and a receiver for performing the same

A method for receiving data in an Ultra-Wideband (UWB) wireless communication system, the method comprising:

• receiving a plurality of signal pulses that are each transmitted a number of times;
• calculating a plurality of correlation values by applying a correlation mask to each of the plurality of signal pulses;
• summing the correlation values that have a value less than a threshold value;
• and
• detecting a bit corresponding to each signal pulse based on a result of the summing,
• wherein the threshold value is acquired based on a near/far interference ratio and a near-interference pulse ratio of signal pulses,
• wherein the near/far interference ratio comprises a ratio of a near-interference amount to a far-interference amount, the near-interference amount and the far-interference amount being comprised in the plurality of signal pulses, and
• wherein the near-interference pulse ratio comprises a value acquired by measuring a ratio of distorted signal pulses due to the near-interference among the signal pulses.

An apparatus for receiving data in an Ultra-Wideband (UWB) wireless communication system, the apparatus comprising:

• a receiver to receive a plurality of signal pulses that are each transmitted a number of times;
• a correlation unit to calculate a plurality of correlation values by applying a correlation mask to each signal pulse of the plurality of signal pulses;
• a threshold value determinator to acquire a threshold value based on a near/far interference ratio and a near-interference pulse ratio of signal pulses;
• a near-interference eliminator to eliminate the near-interference from the plurality of correlation values, the near-interference being a correlation value of the plurality of correlation values having a value greater than the threshold value;
• and
• a bit detector to sum the plurality of correlation values having a value that is not greater than the threshold value, and to detect a bit corresponding to each pulse signal,
• wherein the near/far interference ratio comprises a ratio of a near-interference amount to a far-interference amount, the near-interference amount and the far-interference amount being comprised in the plurality of signal pulses, and
• wherein the near-interference pulse ratio comprises a value acquired by measuring a ratio of distorted signal pulses due to the near-interference among the signal pulses.
