The signal is not one continuous scheme. In the example provided with 5 minutes of this 2.4 KHzKiloHertz (kHz) 10^3 Hz signal, it features bursts with a varying order and duration of :
- 200Hz wide FSKFrequency-Shift Keying-2 at a -600 HzHertz (Hz), unit of frequency, defined as one cycle per second (1 Hz). offset
- FSKFrequency-Shift Keying-5 seemingly idle synchronization
- possible PSKPhase-Shift Keying
- possible 36-tone OFDMOrthogonal Frequency-Division Multiplexing
Assuming it is actually OFDMOrthogonal Frequency-Division Multiplexing, most likely parameters are : 36-tone OFDMOrthogonal Frequency-Division Multiplexing with 16 msmilliseconds (.001 of a second) OFDMOrthogonal Frequency-Division Multiplexing symbol duration, 4 msmilliseconds (.001 of a second) guard interval (20ms total) and 62.5 HzHertz (Hz), unit of frequency, defined as one cycle per second (1 Hz). spacing.
