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.

摘要： A multiple access digital communication method in ultra-wideband (UWB) radio access network is provided. More specifically, a multiple access technique in UWB communication channels is provided where UWB communication channels can be more efficiently used and collisions between multiple access user nodes can be more effectively avoided when the channels have a great multiple path fading. The digital communication method for use in an uplink in a UWB communication system includes the steps of: receiving data symbols from respective nodes, in which the data symbols are transmitted according to respective orthogonal time hopping patterns; checking whether there is a collision of the orthogonal time hopping patterns; and decoding the data symbols depending on whether data symbols of nodes involved in the collision of the orthogonal time hopping patterns are the same.
