Hi Sebastian -
Thanks for putting together this final blog post, and the promo video is
great. It's great to hear that you hit all of your milestones, and I'm very
happy to see a successful v1.0.0 release in CGRAN. Excellent work!
Nice work putting together a good selection of example flowgraphs
Hi all!
GSoC 2016 is coming to an end and I have written a final blog post about
gr-inspector:
https://grinspector.wordpress.com/2016/08/19/week-13-the-end/
All milestones could be reached. Also have a look if you're interested in
the promo video!
Cheers,

Hi all,
it's the second last week of GSoC 2016 and I've dealt with the last (small)
issues that accumulated during the last weeks.
Read about it here:

Stay tuned next week for the pybombs and promo video release!

Hi,
GSoC week 11 is over and I have updated my block with what I have been
doing this week:
https://grinspector.wordpress.com/2016/08/05/week-11-let-the-music-play/
Thanks to an universal resampler in the Signal Extractor it is now possible
to demodulate detected FM signals.
Cheers

Great work!

Hi all,
week 10 of GSoC is over and I managed to implement an OFDM sync block:
https://grinspector.wordpress.com/2016/07/29/week-10-sync/
Since I make good time, I will try to add a FM demod block to the toolbox.
Target is to have one example workflow from Ether to demod data (= sound).

Hi list,
in week 9 of my GSoC I finally managed to implement a working OFDM
parameter estimation block. Read here about it:
https://grinspector.wordpress.com/2016/07/22/week-9-ofdm-finale/
Next up is a frequency and timing synchronization block.

Hi Martin,
I have no problem with keeping the 'old' algo in the toolbox. But still I'm
not sure if it is usable in real-world scenarios with sampling offsets.
Maybe someone can improve it if interested.
Cheers, Sebastian

To clarify, if Koslowski's algorithm (since you already coined the
term...) is *as* good as your original one, but also faster, you should
not have duplicates. But if you did all the work to create software that
actually outperforms the fast algorithm in some other aspect, there's no
harm in keepin
Sebastian,
thanks for sharing, and your awesome work! I would suggest if you have
an algorithm with great detection characteristics, you should keep it.
If you want another suboptimal but fast one, create a second block (or
whatever it is). The first algorithm did cost you time, and its superior

Hi Ben,
thanks for your interest. The manual signal selection is like the demod
function in gqrx. You can move and resize an overlay that will determine
the signal information that gets passed downstream. I have not dealt with
AMC for now, but based on my own experience with manual
modulation reco
Hi Sebastian -
Thanks for the great update!
I'm curious how the "manual selection with the mouse" will work? For some
of the back-end processing that is going on, like Chris's AMC work, not
selecting all of the bins of the signal seems like it could seriously
impact the success of those functions

Hi Jan,
thanks for the feedback!
PFBs are a topic I discussed with my mentors and we decided to not use them
because of the following reasons. When using PFBs, there is a trade-off
between band resolution and calculation effort (few filters lead to low
number of possible frequency bands, many filt
Hey Sebastian,
great work in your first week. Looking pretty good.
One question though. At the end you propose to seperate the signals with a
filterbank of xlating FIRs. Is there a use case or a way to do that with a
polyphase filterbank? Cause multiple FIRs are going to become a major
burden for

Hi Ben,
thank you for your interest and feedback!
To your first question: The desired behaviour of the signal detector would
be to recognize a multi-carrier system (like OFDM) as one signal, since all
the carriers are needed to transmit the information. If the frequency
resolution is very fine, a
Hi Sebastian -
Thanks so much for the great update! I have two questions:
You mentioned in your blog post that all adjacent bins will be interpreted
as one signal in your detection block, which then gets passed downstream to
the analysis portion of your design. Can you comment on how this might b
