Hi Miguel,
I assume your Vector Source is not set to "Repeat"? Or how does your
Flow graph Terminate?
Generally, no block can modify its input buffer; hence, what File Sink
"sees" as an input number sequence must be identical (unless we really

Hi Rohit,
can you make sure to use the "reply" button in your mail client to
directly reply to my mails? That way, the context is preserved, and mail
clients can show your discussion on the mailing list as one thread,

Hey Rohit,

Hi,
I'm using CBX daughter board which supports from 1.2GHz to 6.0GHz with
ANT500 (from 75MHz to 1GHz).
Actually, I didn't know this antenna coverage.
I have two question.
i) Is there any problem when I use ANT500 with CBX ?
I have tested QAM and QPSK performance using OFDM using those devices

Hi,
There is no problem using these antennas with your board, as long as you
terminate them correctly, 50 O.
You choose your antenna based on your coverage, not your board. So what
coverage do you need?

Hm, strange, the Cheetah package on my PC is definitely written with

Hi,
ANT supports 75MHz - 1Ghz, but CBX supports 1.2GHz - 6GHz.
I am confusing coverage of antenna and daughter board.
What means these range?
Is this situation possible?
- Center frequency 1.5Ghz with ANT500
- Center frequency 325MHz with ANT500
Thanks

Hi
1) Center frequency 1.5 Ghz. ANT500 performs well from 75Mhz - 1 Ghz.
Outside its optimal range, you can find better antenna.
2) Center frequency 325 Mhz. This is within ANT500's nominal range, but
outside your board's range. You will have problems with your board.

Pretty solid! I haven't fully understood the bitbake thing, but I like
the idea of becoming more involved in the embedded world, without trying

Hi SangHyoeg:
If you want a good introduction to antennas, designed for the non-professional

Communications”. As an engineer, you will find the material easy to read and

Hi Sean,
Thanks for taking the time. You're definitely right about setting the
parameters for the scrambler/descrambler, it seems like I can get my
descrambled signal to look pretty close to my original signal or I can
totally screw it up by changing the parameters. What I don't know is
whether
I've always used a "skip head" block after the descrambler to remove these
erroneous items that come out. "skip head" will drop whatever number of
items on the floor you tell it to and there after pass everything.

Ah, thanks for that, I tried looking for a block that does this and figured
it would be called something like "drop ..." or "discard ...".
This does work but it has it's one problem: My tagged stream to PDU block
has to wait for all the bytes specified by the length_tag to come in before
it forms

Dear Fikrat,
the physical power depends on your waveform. Generally, the power is
always $P(t) = U(t)\cdot I(t)$, which, thanks to Ohm's law ($U=R\cdot
I\rightarrow I = \frac UR$) is $P(t) = \frac{U^2(t)}{R}$. As you might
know from the basics of electrical engineering, one can represent
harmonic

Well, the point is that that tool installs Cheetah somewhere Python can
find it; you shouldn't be adding c:\cheetah-2.4.4 to your python search
path, but the path Cheetah was installed to. In your case maybe
something like "C:\\Python26\\lib\\site-packages\\cheetah" ?
Hope that helps!

As an attachment I send the .grc on which I'm doing tests.
So:

- bypassing Head and Throttle -> huge file
- bypassing Head, Throttle and Encoder -> fine

To answer your question, yes, Packet Encoder is really old and IMHO
should be deprecated in favor of the architecture you'd find in the
ofdm_tx.grc example (should be installed somewhere like
/usr/(local/)share
Who is calling pygraphviz? If we need this for GNU Radio, we probably

gr-perf-monitorx. It's just been the kind of thing that everyone that uses
it already has and no one tracks it. There's a couple of minor deps for
utilities like this that sneak through the cracks, but they're very hard to
keep track of until you run this on a brand new image.

gr-perf-monitorx requires python-networkx, which (I think) is an untracked
