Kartik,

I was joking about renaming it. Waterfall plot is a common term, even if
it's upside down, people would get more confused with any other name.

Cheers,
Martin

Luca,

I sure hope this wasn't your last mailing list post though :)
I'm very glad you've said you would keep working on this.

Re: [Discuss-gnuradio] OFDM Preamble

[Edwin Li]

Hi Adhitha,

I haven't used the "OFDM Insert Preamble" module before. But in my
understanding, in tx_ofdm.grc, "OFDM Carrier Allocator" does the job of
"OFDM insert preamble". It uses "sync word" instead of "preamble". I think
they are the same thing. As for FFT length, keep it the same as your other
OFDM modules. Note that the length of a sync word must be the same as FFT
length.

Regards,
Edwin

[Discuss-gnuradio] Packet encoding example (Packet_loopback_hier.grc)

[mehtap özkan]

Thanks to Marcus Müller I became aware of the Packet TX and RX blocks.
 I use the Packet_loopback_hier.grc example. However the example is set to
2 samples per seconds=sps. When I try to increase sps=100, the number of
taps of the RRC filter becomes( 5*sps*nfilts) exceeds its limit.
 I get
../.grc_gnuradio\packet_rx.py", line 49, in __init__
self.mark_delay = mark_delay = mark_delays[sps]
IndexError: list index out of range

Is there another way to increase the speed limit?

Thanks

[Discuss-gnuradio] [GSoC 17] DAB: Last Update

[Moritz Luca Schmid]

Hi everyone,

here is my last blog post 
. It 
contains my latest progress and a cool gource video of the gr-dab git 
commit history during GSoC that you can also find on YouTube 
.


Next week, I am submitting my final GSoC code after fixing the last 
(until now ;) known bugs.


After GSoC I am planning to reimplement the OFDM synchronization of 
gr-dab. Read more about it in the post.



Cheers

Luca

Hello,

Yes. In fact, it is one of the reasons of having the module! If you have a
web server and domain name configured for redirect/proxy to the system
using the hardware, you can share it over the Internet.

[Adhitha Dias]

Hi,

Could anyone please help me to set the input parameters in "OFDM Insert
Preamble" OOT in GNURadio? It has 2 parameters FFT Length, and Preamble.
Where should it be used in the tx_ofdm.grc example. Thank you for the help
in advance.

Adhitha Dias

That looks cool

Does that mean people could access a waterfall remotely ?

I watch the waterfall for satellites
