I have a block I implemented, and I use it inside a GRC flowgraph with many
in-tree blocks.
I want to reference one of those blocks from my own block (call one of its
methods).
Is it possible in GRC without manual modification of the generated Python
file?
Hi Gilad,
it is possible to pass references to other blocks to your custom block.
But you should avoid this implementation. First off, another block is
scheduled in another thread. This might cause runtime issues.
If you need status information from another block, add a message port
that
Hello Luca!
Thank you for showing interest in GSoC (once again! :) )
Your idea sounds very cool and also very useful for users that want to have
a first approach to MIMO, and you did your homework checking where this
idea fits in the tree, and propose reuse of code, which is fantastic. As
you
Hi Kevin,
Good to hear from you. I did receive your amplifier, but its been too
cold for me to work on my telescopes in my barn. Hopefully this weekend
I’ll give it a try.
Concerning the Vector Average and Vector Median Blocks, it would be great
to unify our Radio Astronomy contribution.
Hi Marcus,
So I did an implementation using a similar logic as in gr-cdma
(courtesy Achilleas)
after smoothening the input. Once the correlation rose above a threshold, I
essentially started taking 1K point FFTs and correlated the power
distribution with the Carrier Distribution Sequence as
Hi Anshul,
regarding frequency correction (although I do not know the details of DVB)
my understanding is that there is a repeated training sequence, let's say
it is repeated N times.
If this is true, then the output of the MF (matched to one of the training
chunk) will give N peaks, each of

The method I want to call is thread-safe, and the target block doesn't
support the required message.
Regardless, I only need it for quick prototyping so I don't care at this
stage if this is clean or not. This is an experimental GRC flowgraph for me.
How do you pass a reference to the target
Hi Luca,
great to hear from you again!
MIMO is definitely a topic that deserves to be tackled by GNU Radio. Your
idea seems well thought of and sensible (and of course your last year’s
work speaks for itself). If I understand correctly, your proposed approach
would only cover the MIMO-OFDM case.
Greeting Mr Muller and community,
I have made improvement in the proposal. Have a glimpse of it,
Some queries:
What exactly should I include in 'Implementation'? I have put generic
decoder code and sample code for optimal implementation of FEC codes.
What can be the outcome of a specific
I don't understand – you still haven't addressed any of the mandatory
things that I complained were missing. Since having all the formal
requirements and information and specified on the wiki page is a
**requirement**, we can't work with the proposal in its current shape!
Best regards,
Marcus
Hi Harshit Gupta,
thanks for showing up and being interested in GNU Radio!
I'm very happy that someone with an information theory background
decided to give channel code implementations a try.
From a quick scan of the proposal, I'd say that you have not adhered to
all the mandatory things on
