OK, great.

This is due to the fact a recent pull request has not yet been merged into gnuradio.

SO the constellation module does not have yet the "constellation_8psk_natural"

constellation.

There is a simple fix to that:

please go to your gr-cdma/python directory
and edit the file

cdma_parameters.py

In particular in line 124 change "digital.constellation_8psk_natural" with "digital.constellation_8psk".

Now you have to make, sudo make install, sudo ldconfig one more time.

Once you do that, please open a python session and redo

>>> from cdma import cdma_parameters as cp

and let us know what you get.

(if you don't get any errors you are ready to go!)

Frank,

Please do the following and report to us what you get.

Open a python session and write

>>> from cdma import cdma_parameters as cp

What is the result of this?

Hello Sir, I just tried that and the first the hier block "amp_var_est_hier.grc gets compiled with no issues.

However the others are producing errors in certain blocks and can therefore not compile. The error states "name 'cp' is not defined.

And the import box is showing this error "Bad import syntax:import cdma.cdma_parameters as cp". This is where I am stuck at because it seems all the other blocks that are producing errors has this 'cp' in it somehow.

Frank,

you have to follow the procedure in README by compiling ONE file at a time,
and RELOADING the blocks as you go on, ie,

Load the hier block "amp_var_est_hier.grc",

Compile it (this little button on GRC that looks like a pyramid, a sphere and an arrow)

Reload it (this little circle button on GRC)

Load "cdma_tx_hier.grc",

compile it as before

reload

Load "chopper_correlator.grc",
compile
reload


etc...
"cdma_rx_hier.grc", "cdma_tx_hier1.grc", "cdma_rx_hier1.grc" and compile them

Hello Sir, I have read the readme.md file already. My first issue is where it states to "load all the hier blocks and compile them". When I loaded them via the GRC by clicking on "open an existing flowgraph" and selecting the files, I see that they all are missing some variables, information, and even blocks, and are shown as red.
I have taken a picture to show you this. I am using version 3.7.5.1 of GNuRadio by the way

There is no such instruction to be executed!

Please read the README.md file and let us know which one of the detailed instructions mentioned there you don't know how to execute.

Ok. First instruction that I do not know how to execute is the import variable block that says "import coma.cdma_parameters as cp". What exactly am I supposed to be replacing in this section.
