Short Description Russian OFDMOrthogonal Frequency-Division Multiplexing HDR (High Data Rate) Modem. Has three main modes: CISCommonwealth of Independent States (CIS), the former Soviet Republic-45, CISCommonwealth of Independent States (CIS), the former Soviet Republic-60, and CISCommonwealth of Independent States (CIS), the former Soviet Republic-93, corresponding to the number of OFDMOrthogonal Frequency-Division Multiplexing tones in the signal.

Russian OFDMOrthogonal Frequency-Division Multiplexing HDR (High Data Rate) Modem. Has three main modes: CISCommonwealth of Independent States (CIS), the former Soviet Republic-45, CISCommonwealth of Independent States (CIS), the former Soviet Republic-60, and CISCommonwealth of Independent States (CIS), the former Soviet Republic-93, corresponding to the number of OFDMOrthogonal Frequency-Division Multiplexing tones in the signal. For all three modes, there is a carrier located 3300 HzHertz (Hz), unit of frequency, defined as one cycle per second (1 Hz). from the suppressed carrier. In addition, all three modes utilize PSKPhase-Shift Keying OFDMOrthogonal Frequency-Division Multiplexing Modulation.
