I need to check the loopback flowgraph you mentioned, but the header
detection should work down to very low Eb/N0 values.
However, you mention a noise amplitude of 1.5. IIRC, that would yield an
SNR below 0 dB, not 13 dB as you mention.

Hello Marcus,
Wow, Thanks for such an in-depth reply!
I knew I kept a reference for numpy data types about a month ago for a
reason, but forgot how/when/why GNU Radio uses them. Now it's very clear
how the whole conversion in python happens based on the data type.
I'll print this out and work o

Hii,
I am trying to decode qpsk symbols for channel estimation block in python
but there is error in importing digital_swig.
This also happens when i run "qpsk.py" as shown below:
*Traceback (most recent call last):*
* File "qpsk.py", line 32, in *
*import digital_swig as digital*
*ImportErr
qpsk.py can't be run.
It's just a python module containing functionality for QPSK, but no
"main" function or similar.
What are you actually trying to do?
Best regards,
Marcus

Hi all,
I would like to know if there is a way of creating the setup_env.sh file
that pybombs creates for you automatically, when you are installing from
source without pybombs at all. Currently, I cheat by copy and pasting the
pybombs generated file from another computer that used pybombs. What i
Basic unix familiarity is required.
If your shell can't find a program, check that it's in your PATH.
If a program fails to start, make sure the linker can find any necessary
libraries and maybe add them with LD_LIBRARY_PATH
If python can't find a module, check that it's in PYTHONPATH, and any

Got it. Thanks.

Hii marcus,
I am trying to decode the symbols and use the decoded symbols for further
processing in the same python written module. I am not able to call the
"constellation" related functions.
How can i use them ? or is there any "decoder" written in python ?
Thanks !!
