FIELD: physics, communications.
SUBSTANCE: invention concerns communication technology. Invention claims algorithm of power adjustment in feedback line with closed circuit for frequency-hopping orthogonal frequency division multiple access (FH-OFDMA) system. Algorithm of power adjustment corrects user transmission power on the basis of measured actual ratio of carrier waveform to interference (C/I) and ration of received power over thermal noise (RpOT). Algorithm is basically stably and efficient for FH-OFDMA systems with retransmissions.
EFFECT: enhanced efficiency of system operation.
