Abstract  Abstract

The invention claims a whole frequency band is divided into several sub-carriers with and comprises a plurality of sub channel of the wireless communication system each sub-channel comprising a plurality of sub-carriers with. the number of subcarrier groups is equal to the number of base stations included in the system and is through classification of subcarriers with generated in one period. For a particular base station based on the sequence from each group of detecting corresponding subcarrier with. subcarrier with from each group is detected is assigned as a sub-channel of a specific base station. In addition whenever the assigning subchannels changing the index of the sub-carrier group belonging to each sub channel is composed of secondary carrier wave so as to acquire the desired diversity gain.

A wireless communication system that divides an entire frequency band into a plurality of subcarrier bands and includes a plurality of subchannels each of which includes a number of subcarrier bands. The number of subcarrier groups is equal to the number of the base stations included in the system and are generated by classifying the subcarrier bands in a period. For a particular base station corresponding subcarrier bands are detected from each of the groups according to a sequence. The subcarrier bands detected from each of the groups are assigned as a subchannel for the particular base station. Further the indexes of the subcarrier groups to which each of subcarriers constituting a subchannel belongs are changed whenever the subchannel is assigned so as to acquire the desired diversity gain.
