Data signal thought to originate from Japanese Military/Navy. Although 8-Channels are used, it is actually two FSKFrequency-Shift Keying channels duplicated with Orthogonal Frequency-Division Multiplexing (OFDMOrthogonal Frequency-Division Multiplexing) among the other 6 channels for high redundancy.
The signal consists of two independent FSKFrequency-Shift Keying-2 channels which are doubled according to a cross-schema. All four channels use the Manchester code and, with time offset between the two channels, formed using OFDMOrthogonal Frequency-Division Multiplexing.
