You're totally welcome. I had to use -DENABLE_DOXYGEN=ON to actually
make it enable doc building, forgot to mention that.

Hi Murray,
although I am the author of gr-cdma I do not know how to help you with
this. I am using doxygen etc as a user, not a developer, so I wouldn't even
know where to start.
For what it's worth, I have developed and tested this module on Fedora 21.
Hope someone else in the list can help on
Hi,
I'm trying to build gr-cdma in Ubuntu 16.04 following the instructions in
https://github.com/anastas/gr-cdma.
I can build it with
cmake -DENABLE_DOXYGEN=OFF "PATH TO YOUR gr-cdma TRUNK"
But when I enable doxygen it fails. I have installed
sudo apt install doxygen doxygen-doc doxygen-gui
Hi Elisabeta,
could you please post some more info:
what os are you working with
what is your gnuradio prefix
post the entire cdma_parameters.py file
also is this the latest version of gr-cdma from github?
thanks

cdma_tx_hier.grc
i got some errors with the import
Param - Import(import):
Bad import syntax: "import cdma.cdma_parameters as cp".
how to solve
Ekko,
Do not worry about grc for now. You first have to fix the python import
error.
It is very unusual that you have downloaded the gr-cdma in the directory
"/home/gr-cdma" .
In the /home directory usually there are user directories and you do not
have permissions, etc...
How do you run all
as you say ,i am using e310,so i run all the command as root
the gnuradio is pre_installed ,so i do not konw where is the gnuradio.

Another suggestion is to install your gr-cdma exactly where your gnuradio
is installed.

Ekko,

(trunk directory)

Looking at the output of the cmake I think I know what is going on:
Your gnuradio installation is not in the standard directory /usr/local/...
So probably your PYTHONPATH variable is not set for python to look there.
You should add the directory
/usr/local/lib/python2.7/site-packages/
in
and now i add a regular user ,run the command again

Ekko,
I can help you with these error messages. They are not supposed to appear.

They are described in the README file of gr-cdma. There are 3 precisely

you can perform simulations and plot BER vs SNR using either of the two

On Monday, January 19, 2015 9:07 AM, Achilleas
I will try the GDB tomorrow and let you know the output response.One more
question. Is the cdma_txrx.grc just for packet transmission with no hardware
attached, while the cdma_tx.grc and cdma_rx.grc are used for real live cdma
transmission with hardware (ex: USRP's)?And I don't really
Indeed, the cdma_txrx is a simulation of the entire tx/rx.
We used it to test our system and everyone can use it if they
don't want to (or cannot) transmit through real hardware.
The separate files cdma_tx and cdma_rx can be used with
real USRPs.

Frank,
please pull the latest version of gr-cdma.
You have to make a small edit in the cdma_parameters.py file
(see updated README file) before you install it.
Once you do that, open a python session and do

This should now give no errors.

In any case they refer to adaptive modulation

For the same reason, constellation_16qam is not in the current
