Abstract
FIELD: communication systems which support multi-access with orthogonal frequency division in particular device and method for adaptive selection of sub-channels. ^ SUBSTANCE: wireless communication system divides whole frequency band onto a set of bands of sub-carriers and includes a set of sub-channels each one of which includes a set of sub-carrier bands. Number of sub-carrier groups equals the number of base stations included in the system and they are created by classification of sub-carrier bands. For a certain base station corresponding sub-carrier bands are detected in each group in accordance to a series. Sub-carrier bands detected in each group are selected as a sub-channel of a certain base station. Further indexes of sub-carrier groups to which each sub-carrier belongs making up the sub-channel change each time when sub-channel is selected to achieve required advantage of separation. ^ EFFECT: ensured time-frequency two-dimensional selection of sub-carriers in OFDMA communication system. ^ 8 cl 5 dwg 2 tbl
