Multiple access digital in ultra-wideband radio access networks

The present invention relates to multiple access digital communication method in ultra-wideband (UWB) radio access network. And more particularly, to a technology capable of efficient use of communication channels in a multi-path fading is severe UWB channel and effectively controlling a collision between multiple access terminals. The present invention relates to a digital communication method in an uplink of a UWB communication system, the method comprising: receiving the data symbols transmitted according to respective orthogonal time hopping patterns from each terminal; Checking whether the collision of the orthogonal time hopping patterns; And a step of decoding the data symbol on the basis of whether the identity of the data symbols of the terminals of a collision of the orthogonal time hopping patterns occurs. Ultra-wideband digital communication, an orthogonal time hopping access method, statistical multiplexing, power consumption reduced, and the frame structure
