FEEDBACK LINE POWER ADJUSTMENT IN ORTHOGONAL SYSTEM

摘要

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. ^ 25 cl, 4 dwg
