I am constructing the flow graph(screen capture, grc) attached.
I am expecting the data at the output of packed-to-unpacked block to be
same as the data at the output of differential decoder, except for some
stray bits in the beginning. When I search for patterns in the transmit
chain, in the receive chain, I don’t get any match. This it the
attached) that I use to compare data in the transmit chain and the
template_len = 20
temp = scipy.fromfile(open("/tmp/diff-encode-out.bin"),
template = temp[100:template_len+100]
match = False
rec = scipy.fromfile(open("/tmp/rec-map-out.bin"), dtype=scipy.uint8,
for i in range(9950):
if (template == rec[i:template_len+i]).all():
The program works for BPSK, but fails to find pattern in QPSK, DQPSK
Would anyone know what is going wrong in my flow-graph?
Thank you in advance.
