Clearly, you have an issue with importing the cdma module into python.

Can you tell me what is the value of the variable  "prefix" in your cdma_parameters.py file?

(you can find it in gr-cdma/python/ directory)

I opened the terminal in gr-cdma folder and ran the following command 

"python"

after that I ran this :

"from cdma import cdma_parameters as cp"

as you told me , 

I received this ,

 

 CDMA PARAMETERS : for adaptive modulation

bits_per_header= 36

symbols_per_header= 36
