快速傅立叶变换程序代码,学信号的同学,可要注意了

# GAd variables
#
# file to be read by commander.p
# each line is turned into a structure entry   	(str)
#     	a default-setting entry			(def)
#     	a usage-printing entry			(usg)
# 	and a command line reading entry	(clr)
# of these, the S, U and C can be disabled by >No S, etc.
# and the D can be disabled by -.

# BND is essentially parameter-free; you only have to decide when to
# give up. For numerical reasons a clipping rule was introduced but it
# only very rarely makes any difference.
# the fudge procedure is not needed but is investigated as a research 
# possiblity.
GAdc->GallagerB d 10 -GAB loops - number of loops after which to use the Gaallager B trick of changing the threshold for bit flip (actually implemented by having the channel info be ignored, j=4)
GAdc->loops	d 200 -GAdloops loops	-	Max number of loops
>No CU
GAdc->loop	d 0 - - - - 
GAdc->include_bias d 2 - - - how much strength to give the bias in early steps of decoding
>CU
GAdc->writelog	d 0 -GAdlogn n - number of states to log
# added 97 02 : write_intermediate_states
GAdc->wis	d 0 -GAdwis p - period with which to write current state
GAdc->wisline	d 40 -GAdwisline l - number of states per line
GAdc->isfile	s - -GAdis  isfile  if(!GAdc->wis)GAdc->wis=1; write entire intermediate states
GAdc->logfile	s - -GAdlog logfile if(!GAdc->writelog)GAdc->writelog=10; for state info
