CHANNEL ALLOCATION SYSTEM FOR MULTIUSER RESOURCE SHARING AND CHANNEL ALLOCATION METHOD FOR MULTIUSER RESOURCE SHARING

摘要

PURPOSE: A channel allocation system for multiuser resource sharing and a channel allocation method for multiuser resource sharing are provided to enable each terminal to maximize a channel diversity gain through multi paths and prevent mutual interference between terminals by assigning an orthogonal channel to each terminal. CONSTITUTION: A channel allocation system for multiuser resource sharing includes terminals(U1,U2,U1',U2',U3',U4') and a base station(20). Respective communication channels are assigned to the terminals. The base station sets at least one group including terminals according to preset signal quality reference. The base station successively selects a communication channel with a larger channel gain from a terminal with low signal quality among communication channels assigned to the terminals in order to assign the channel to a corresponding terminal. The base station controls the terminals to transmit a signal through the assigned channel.
