This is the result after making the prefix modification in the
cdma_parameters.py file and opening a python session:
>>> from cdma import cdma_parametersCDMA PARAMETERS : for adaptive modulation
bits_per_header= 36
symbols_per_header= 36
bits_per_coded_symbol = [2, 3] for [uncoded QPSK, rate 2/3 cc &8PSK]
respectively.
payload_bytes_per_frame= 50
symbols_per_frame= 260
trellis_coded_payload_symbols_per_frame= 216 for [uncoded QPSK, rate 2/3 cc
&8PSK] respectively.
trellis_coded_payload_bytes_per_frame= [54, 81] for [uncoded QPSK, rate 2/3 cc
&8PSK] respectively.
additional_symbols_per_frame= 8 for [uncoded QPSK, rate 2/3 cc &8PSK]
respectively.
additional_bytes_per_frame= [1, 1] for [uncoded QPSK, rate 2/3 cc &8PSK]
respectively.
you have wasted [0.01818181818181818, 0.012195121951219513] percent of bytes
per payload for [uncoded QPSK, rate 2/3 cc &8PSK] with this symbols_per_frame
setting.

yes, please disregard all previous changes.
They have been incorporated in the updated files.
So, please pull a clean copy from github.

Hello Achilleas, thank you I will do that! When I perform this edit in the
python file should I disregard the changes we did yesterday in th
cdma_parameters.py file line 124 which was changing the
"digital_constellation_8psk_natural" with "digital.constellation_8psk" and keep
the orginal code?

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
>>> from cdma import cdma_parameters
This should now give no errors.
Let us know of your progress.

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!)

| 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

because it seems all the other blocks that are producing errors has this 'cp'
in it somehow.

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
