Abstract
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.
