FIELD: communication systems. ^ SUBSTANCE: when two modulation circuits are accessible, information is modulated in compliance with lower-order modulation circuit in case first product of modulation order by peak velocity is lower than first threshold value and in compliance with higher-order circuit in case first product of modulation order by peak velocity is not lower than first threshold value. Product of modulation order by peak velocity depends here on personal computer size, number of Walsh codes, and number of slots per sub-burst. Second product of modulation order by peak velocity is computed using personal computer size, number of Walsh codes, and number of slots per sub-burst. If first product of modulation order by peak velocity does not exceed second threshold value higher than first one, then lower-order modulation circuit is chosen. If second product of modulation order by peak velocity is higher than second threshold value , higher-order modulation circuit is chosen. ^ EFFECT: provision for finding optimal modulation circuit for retransmission. ^ 14 cl, 14 dwg |
