Steve Franke	f2dc394c84	Add ft4 files; ft4sim works, ft4d is work in progress.	2019-01-21 19:31:54 -06:00
Steve Franke	7701516b43	ft2sim now creates a GFSK waveform with BT=1.0. It also adds raised cosine ramp up and down at the beginning and end of the transmission.	2019-01-17 14:01:40 -06:00

Steve Franke	348e7c8ad5	In principle, ft2d can now decode multiple signals. Not yet tested.	2019-01-13 15:44:16 -06:00
Steve Franke	1fb89929a9	Make ft2d slightly more robust. Still very rough.	2019-01-13 10:58:35 -06:00
Steve Franke	cf1fe6c3d6	More work on FT2. New frame format is 16sync + 128codeword. Data chunk is assumed to be 2.5s long. A rudimentary sync routine is implemented which finds the single strongest signal.	2019-01-12 13:28:10 -06:00
Steve Franke	f63f0301eb	Tweak some decoder parameters for better performance.	2019-01-10 10:35:09 -06:00
Steve Franke	e0658f183f	Add simulator (ft2sim.f90) and decoder (ft2d.f90) for experimental medium-fast mode.	2019-01-10 10:20:31 -06:00
