MIL-STD-188-110 Appendix A is a 16-tone OFDMOrthogonal Frequency-Division Multiplexing PSKPhase-Shift Keying signal used to transmit data. As of 110C revision, this mode is being phased out. However it is still used in the US during Armed Forces Day.
PSKPhase-Shift Keying signals are superseding these lesser-performing signals.
A 605 HzHertz (Hz), unit of frequency, defined as one cycle per second (1 Hz). pilot tone is sometimes used for doppler correction. The preamble has both 605 HzHertz (Hz), unit of frequency, defined as one cycle per second (1 Hz). and 1705 HzHertz (Hz), unit of frequency, defined as one cycle per second (1 Hz). umodulated tones used to sync the modem so it may receive the signal clearly. Uses a 75 HzHertz (Hz), unit of frequency, defined as one cycle per second (1 Hz). baudBaud (unit symbol Bd) is the unit for symbol rate or modulation rate in symbols per second. rate in each channel. Uses BPSKBinary Phase-Shift Keying (1 bit per symbol) for 75, 150, 300, and 600bps (135 and 315 degrees, to remain the same as DQPSKDifferential Quadrature Phase-Shift Keying's phases), and uses DQPSKDifferential Quadrature Phase-Shift Keying for 1200 and 2400bps.
