Thanks Ron, that's correct -- just a technicality: The rolloff is in
*samp
If the rolloff parameter is zero, the block does not
do any pulse shaping. The rolloff parameter is in
symbols, and must be at least 2 and less than or
equal to CP length.

I want to test my understanding about ofdm_cyclic_prefixer.As this

For continued support with various and older systems, we don't support

Hi list,
Could anyone tell me about the C++11 support in gnuradio?

I have tried that, and can disprov
Hi Mostafa,
this is no good. If you don't tell us why and how you would want to do
that, we can't discuss if and how GNU Radio is lacking.
Really, the GNU Radio architecture wasn't meant for this kind of flow
control, but that's less of a shortcoming than a design choice, keeping
flow graph design
Activecat,
I think change my topology to get rid of this things. :)
However, I still believe in that the GNURadio fails in this scenario.
As we have throttle or message_strobe blocks, I need to have a source which
generates items controlled by another block.
I'll try to see this problem in anothe

Not true. If your block can't produce something, it's not GNU Radio's
fault your downstream blocks don't have anything to
Hi Marcus,
By mentioning that I spent many hours I wanted to say I'm hardly stuck on
this problem yet! :)
You said the there is no problem that we wait on the source to produce as

processing!! In other word, when the source
Mostafa,
I know you've been working many hours on this :) so don't worry, you're
being heard.
Nevertheless, GNU Radio is surely not calling the asking the source
"crazily" to produce items.
GNU Radio is a streaming-into-buffers architecture, which means that the
runtime will ask a source to prod
Hi Mike,
No, the throttle isn't a source! It just controls the flow of items in an
specific time interval. I don't want this! I want cognitively tell the

message can do this for the source). But the scheduler crazily wants
The "Throttle" block is required if you are not using any external hardware:

Hi,
I worked on GNURadio for many hours. After all, I prepared my blocks in
c++. However, the source by which I produce random bits (items with
sizeof(char) ) doesn't work properly! By properly I mean, I wanted GNURadio
to lead me control how it's going to call the *source.* It's crazily
