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
|
|
