bpdecode174_91.f90

For (174,91) code, move CRC generation and testing into encode and decode routines. Make ldpcsim174_91.f90 work with the new encode/decode routines.

2018-06-17 08:44:10 -05:00

chkcrc13a.f90

Create chkcrc13a.f90. Should chkcrc12a, chkcrc13a, and chkcrc14a be combined into one routine?

2018-06-16 09:04:51 -05:00

chkcrc14a.f90

Make two sync passes, one for each sync array. Label candidates with their type and decode accordingly.

compress.f90

Move subroutine h1() to its own file, h1.f90.

foxfilt.f90

Several enhancements to DXpedition mode:

2017-12-27 21:06:57 +00:00

foxgen_wrap.f90

Reconfigure foxgen.f90 for 77bit messages. Fox now transmits only 77bit messages.
