=== AP Decoding
|
||||
|
||||
With the QRA64 decoder Nico Palermo, IV3NWV, introduced a technique
|
||||
for decoding with the aid of information that naturally accumulates
|
||||
during a minimal QSO. This _a priori_ (AP) information can be
|
||||
used to increase the sensitivity of the decoder.
|
||||
|
||||
When an operator decides to answer a CQ, he already knows his own
|
||||
callsign and that of his potential QSO partner. He therefore knows
|
||||
what to expect for at least 56 of the 72 message bits in a
|
||||
standard-format response to his call. The _WSJT-X_ decoders for QRA64
|
||||
and FT8 can use these AP bits to decode messages containing them with
|
||||
higher sensitivity than otherwise possible.
|
||||
|
||||
We have implemented AP decoding in slightly different ways in QRA64
|
||||
and FT8. To provide some explicit examples for users, we provide here
|
||||
a brief description of the FT8 behavior.
|
||||
|
||||
The FT8 decoder always tries first to decode a signal without using
|
||||
any AP information. If this attempt fails, and if *Enable AP* is
|
||||
checked on the *Decode* menu, a second attempt hypothesizes that the
|
||||
message contains callsigns MyCall and DxCall. If the QSO has
|
||||
progressed to the point where signal reports have been exchanged, a
|
||||
third attempt hypothesizes that the message contains the known
|
||||
callsigns followed by RRR, RR73, or 73.
|
||||
|
||||
AP decoding attempts effectively set the AP bits to the hypothesized
|
||||
values, as if they had been received perfectly. The decoder then
|
||||
proceeds to determine whether the remaining message and parity bits
|
||||
are consistent with the hypothesized AP bits. If a codeword is found
|
||||
that the decoder judges to have high (but not overwhelmingly high)
|
||||
probability of being correct, a ? character is appended when the
|
||||
decoded message is displayed. Decodes thus marked are not sent to
|
||||
{pskreporter} to avoid occasional misleading spots of false decodes.
|
||||
|
||||
Successful AP decodes are always labeled with an end-of-line indicator
|
||||
of the form aP, where P is one of the single-digit AP decoding types
|
||||
listed in Table 1. For example, an a2 designator says that the
|
||||
successful decode used MyCall as hypothetically known information.

=== Decoded Lines
|
||||
|
||||
Displayed information accompanying decoded messages generally includes UTC,
|
||||
signal-to-noise ratio in dB, time offset DT in seconds, and
|
||||
audio frequency in Hz. Some modes include additional information such
|
||||
as frequency offset from nominal (DF), frequency drift (Drift or F1),
|
||||
or distance (km or mi).
|
||||
|
||||
There may also be some cryptic characters with special meanings
|
||||
