CISCommonwealth of Independent States (CIS), the former Soviet Republic-112 OFDMOrthogonal Frequency-Division Multiplexing signal. Has a preamble of 8 Tones (including carrier), then a 56 tone OFDMOrthogonal Frequency-Division Multiplexing preamble before entering into the 112 tone data transmission. Each channel uses DQPSKDifferential Quadrature Phase-Shift Keying at 22.22 baudBaud (unit symbol Bd) is the unit for symbol rate or modulation rate in symbols per second.. As with all MPSKMultiple Phase-Shift Keying CISCommonwealth of Independent States (CIS), the former Soviet Republic signals, there is a pilot tone 3300 HzHertz (Hz), unit of frequency, defined as one cycle per second (1 Hz). from the suppressed carrier.
