The code used by the QRA64 mode is the code: QRA13_64_64_IRR_E: K=13
N=64 Q=64 irregular QRA code (defined in qra13_64_64_irr_e.{h,c}).
This code has been designed to include a CRC as the 13th information
symbol and improve the code UER (Undetected Error Rate). The CRC
symbol is not sent along the channel (the codes are punctured) and the
resulting code is still a (12,63) code with an effective code rate of
R = 12/63.

Here we simulate the following (dummy) QSO:
1) CQ IV3NWV
2) IV3NWV K1JT
3) K1JT IV3NWV 73
4) IV3NWV K1JT 73
No message repetition is attempted
The QSO is counted as successfull if IV3NWV received the last message
When mode=QRA_AUTOAP each decoder attempts to decode the message sent
by the other station using the a-priori information derived by what
has been already decoded in a previous phase of the QSO if decoding
with no a-priori information has not been successful.
Step 1) K1JT's decoder first attempts to decode msgs of type [? ? ?]
and if this attempt fails, it attempts to decode [CQ/QRZ ? ?] or
[CQ/QRZ ?] msgs
Step 2) if IV3NWV's decoder is unable to decode K1JT's without AP it
attempts to decode messages of the type [IV3NWV ? ?] and [IV3NWV ?].
Step 3) K1JT's decoder attempts to decode [? ? ?] and [K1JT IV3NWV ?]
(this last decode type has been enabled by K1JT's encoder at step 2)
Step 4) IV3NWV's decoder attempts to decode [? ? ?] and [IV3NWV K1JT
?] (this last decode type has been enabled by IV3NWV's encoder at step
3)
At each step the simulation reports if a decode was successful. In
this case it also reports the type of decode (see table decode_type
above)
When mode=QRA_NOAP, only [? ? ?] decodes are attempted and no a-priori
information is used by the decoder
The function returns 0 if all of the four messages have been decoded
by their recipients (with no retries) and -1 if any of them could not
be decoded

If mode=QRA_NOAP, K1JT decoder attempts to decode only msgs of type [? ? ?].
If mode=QRA_AUTOP, K1JT decoder will attempt to decode also the msgs
[K1JT IV3NWV] and [K1JT IV3NWV ?].
In the case a decode is successful the return code of the qra64_decode function
indicates the amount of a-priori information required to decode the received
message according to this table:

rc=8 [CALL CALL GRID] AP72
rc=9 [CQ CALL ?] AP55
rc=10 [CQ CALL ] AP70
rc=11 [CQ CALL GRID] AP70
The return code is <0 when decoding is unsuccessful
This test simulates the situation ntx times and reports how many times
a particular type decode among the above 6 cases succeded.

QRA64 Mode Tests
2016, Nico Palermo - IV3NWV
---------------------------
Syntax: qra64 [-s<snrdb>] [-c<channel>] [-a<ap-type>] [-t<testtype>] [-h]
Options:
-s<snrdb> : set simulation SNR in 2500 Hz BW (default:-27.5 dB)
-c<channel> : set channel type 0=AWGN (default) 1=Rayleigh
-a<ap-type> : set decode type 0=NOAP 1=AUTOAP (default) 2=USERAP
-t<testtype>: 0=simulate seq of msgs between IV3NWV and K1JT (default)
1=simulate K1JT receiving K1JT IV3NWV JN66
2=simulate fast-fading routines (option -c ignored)
Options used only for fast-fading simulations:
-b : 90% fading bandwidth in Hz [1..230 Hz] (default = 2.5 Hz)
-m : fading model. 0=Gauss, 1=Lorentz (default = Lorentz)
-q : qra64 submode. 0=QRA64A,... 4=QRA64E (default = QRA64A)
-h: this help
#############################################################################
Usage example:
qra64 -c2 -t2 -a2 -b50 -m1 -q2 -s-26.0 -n50000
Simulate a fast-fading channel (-c2)
Evaluate decoder performance (-t2) with
USER_AP (-a2)
B90 = 50 Hz (-b50)
Lorentz model (-m1)
submode QRA64C (-q2)
Input SNR = -26.0 dB (-s-26.0)
Simulate 50000 transmissions (-n50000)
(type qra64 -h for command syntax)
Command Output:
Input SNR = -26.0dB ap-mode=USER AP
Simulating the fast-fading channel
B90=50.00 Hz - Fading Model=Lorentz - Submode=QRA64C
Decoder metric = Matched to fast-fading signal
