=== AP Decoding
The _WSJT-X_ decoders for FT4, FT8, JT65, and QRA64 include optional
procedures that take advantage of naturally accumulating information
during a minimal QSO. This _a priori_ (AP) information increases
sensitivity of the decoder by up to 4 dB, at the cost of a slightly
higher rate of false decodes.
The _WSJT-X_ decoders for FT4, FT8, JT65, QRA64, include
procedures that use naturally accumulating information during a
minimal QSO. This _a priori_ (AP) information increases sensitivity
of the decoder by up to 4 dB, at the cost of a slightly higher rate of
false decodes. AP is optional in FT8, JT65, and QRA64, but is always
enabled for FT4.
For example: when you decide to answer a CQ, you already know your own
callsign and that of your potential QSO partner. The software
therefore "`knows`" what might be expected for at least 57 message
bits (28 for each of two callsigns, 1 or more for message type) in the
next received message. The decoder's task can thus be reduced to
bits (28 for each of two callsigns, one or more for message type) in the
next received message. The decoder's task is thus reduced to
determining the remaining 15 bits of the message and ensuring that the
resulting solution is consistent with the message's parity symbols.

! PURPOSE: Supplement ISO-C-Binding to provide type aliases and interfaces
! to common ISO-C string functions to aid working with strings.
! AUTHOR: Joseph M. Krahn
! STATUS: Still in development. Reasonably complete, but somewhat limited testing.
!
! The idea is to provide type aliases for all ISO-C types, so that the
! Fortran interface code more explicitly defines the actual C interface.
! This should be updated to support F2008 variable-length allocatable
! strings.
!
! Entity names all have the "C_" prefix, as with ISO-C-Binding, with a
! few exceptions.
!
! Sourced from: http://fortranwiki.org/fortran/show/c_interface_module
!
! One FORALL statement reverted to a DO loop to avoid a gfortran 4.9.2 ICE

! The C_ prefix is not used because it is just an ASCII character.

! NOTE: In C, "char" is distinct from "signed char", unlike integers.
! The plain "char" type is specific for text/string values, whereas
! "signed char" should indicate 1-byte integer data.
!
! Most ISO-C systems have wide chars "wchar_t", but Fortran compilers
! have limited support for different character kinds. UTF encoding
! adds more complexity. This should be updated as Fortran compilers
! include support for more character types.
