Characteristics[edit]

RAC-ARQAutomatic Repeat reQuestAutomatic Repeat Query uses FSKFrequency-Shift Keying at 150 BdBaud (unit symbol Bd) is the unit for symbol rate or modulation rate in symbols per second. or 267 BdBaud (unit symbol Bd) is the unit for symbol rate or modulation rate in symbols per second. with a wide shift of 800 HzHertz (Hz), unit of frequency, defined as one cycle per second (1 Hz)..


Samples[edit]

266 BdBaud (unit symbol Bd) is the unit for symbol rate or modulation rate in symbols per second. 150 BdBaud (unit symbol Bd) is the unit for symbol rate or modulation rate in symbols per second.
