|
|
|
|
(copy `bch_ecc.c`) <br />
|
|
|
|
|
`gcc -c demod_dft.c` <br />
|
|
|
|
|
`gcc rs41dm_dft.c demod_dft.o -lm -o rs41dm_dft` <br />
|
|
|
|
|
`gcc dfm09dm_dft.c demod_dft.o -lm -o dfm09dm_dft` <br />
|
|
|
|
|
`gcc m10dm_dft.c demod_dft.o -lm -o m10dm_dft` <br />
|
|
|
|
|
`gcc lms6dm_dft.c demod_dft.o -lm -o lms6dm_dft` <br />
|
|
|
|
|
`gcc rs92dm_dft.c demod_dft.o -lm -o rs92dm_dft` (needs `RS/rs92/nav_gps_vel.c`)
