FIELD: technological processes.
SUBSTANCE: method of subchannel separation in transmitter of cellular communication system of orthogonal frequency division multiple access (OFDMA), where all frequency band includes multiple bands, moreover, each of bands includes multitude of discretization elements, and each of discretization elements includes multiple subcarriers. Method constitutes division of preset time interval into time interval of subchannel with adaptive modulation and coding (AMC) and time interval of diversity reception subchannel; any of multiple bands is selected in the time interval of subchannel with AMC; preset number of discretization elements is selected from multiple discretization elements in the selected band, and selected discretization elements are separated to subchannel with AMC.
EFFECT: increases accuracy and information density of the method.
