Hi All,
@Marcus @activecat @Martin Thank you all for your help. We were
able to solve the problem we had for itemsize greater than or equal to
8192. We used set_output_multiple(fft_length) in the constructor and it
worked. Now it is working for any input fft length.
So at the input of
Hi Activecat,
Thanks for the reply.
As suggested by you, I used Stream Mux and it worked for me.
Now I want to de-multiplex the output of Stream Mux so as to get back both
the inputs separately.
If you have any suggestions, please let me know.
Thanks and Regards,
Dushyant

Let's change the print statement to below, recompile, run and paste the
console output here.
std::cout al_enc::work: noutput_items= noutput_items
std::endl;

Hi all,
The system configuration proposed by Dushyant with encryption after
channel coding can work in case of stream ciphers. This is how it is
done in GSM. But encryption GSM is a very bad example of application of
cryptography. Channel coding will add some known relations between
information

Hi Piotr, hi Dushyant,
GSM
of course, that's true; but it's, as you said, widely agreed upon that
this is security-wise a bad design choice; and it drastically complicate
design of such a transmission system (because you can't check
transmission correctness before decryption).
With stream

Activecat,
I am sorry, I pasted the wrong qa code. I changed value
of n to n=1024 and then when i printed it, I got the output I pasted above.

Yeah. I also think some configurations on my machine are not correct. Here

I am building a hierarchical block for an OFDM tranceiver (two classes in
the same py file) and I was wondering if I could save time by using the old
transmit_path and receive_path scripts. Would they work with the OFDM
modulator and demod from the default build?
Thanks

I think the default GNU Radio search path is /usr/share/gnuradio/grc/blocks
because all existing blocks are stored within this directory. I added the
new path into GRC_BLOCKS_PATH variable.
export GRC_BLOCKS_PATH=/usr/local/share/gnuradio/grc/blocks:$GRC_BLOCKS_PATH
Now I can see the howto block
Hi:
Thank you in advance.
I have two simple question:
1.In the grc,i see a block: header_payload_demux
It has 3 input:in,trigger,header_data.But i see the
header_payload_demux_impl.cc:iosignature::make2(1,2,..,..).But it has 3
input,why?
Thank you.
