Hi all,
I have a question about the channel filter usage in OFDM PHY.
In the benchmark, there is a channel filter used before ofdm syn.
In the new OFDM PHY, especially in the GRC example, there is not such
a block. So, should I use a channel filter when i want to using the New
OFDM P
OK, it appears a previous install hid an extra libvolk in
/usr/lib/x86_64-linux-gnu, removing that everything is working well so far,
thank you for the help everyone.

I am new to linux and GNURadio. I don'g follow where the 1 bit/byte is coming
from. Does the audio source not deliver 8bit/sample or how do you figure that
out? I don't see anything such as "gnuradio>digital>generic_mod_demod.py " in
my directories. Thanks for the help.

Hi Everyone,
>From the tutorial on out of tree module I followed how to install a block,
and access it in GRC.
Now I have a block, "encoder.py" but the actual encoding operation defined
in another class in file "gf2mat.py" . Inside the work function I just call
that operation.

Hi Manu, Tracie,
I wouldn't worry about this for now. I'm assuming this is for your
GSoC project? If so, just keep going and make sure you get the math
right. You'll want to move this into a C++ block eventually,
anyways,
and do further optimizations there. We can worry about this problem

Tom,
Yes, it is for my GSoC project. Till now I have prototyped in python
encoder, decoder and construction of LDPC codes from Reed Solomon codes.
The encoder and decoder input sizes vary based on the code block length and
dimension.
I hope to switch gears to C++ soon.
Thanks.
