Perhaps you should try some spelling variations:
"advanced communications of python programming" » "and communications of python programming" (Expand search), "brand communications of python programming" (Expand search), "broadband communications of python programming" (Expand search), "advanced communications on python programming" (Expand search), "advanced communications in python programming" (Expand search), "advanced communications _ python programming" (Expand search)
"_ convolutional coding coding program" » "_ convolutional codes coding program" (Expand search), "_ convolutional code coding program" (Expand search), "_ convolutional long coding program" (Expand search), "_ convolutional coding cloning program" (Expand search), "_ convolutional coding loading program" (Expand search), "_ convolutional coding cooling programs" (Expand search), "_ convolutional coding decoding program" (Expand search), "_ convolutional coding using program" (Expand search), "_ convolutional coding canine program" (Expand search)

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"_ convolutional coding coding program\") OR (\"advanced communications of python programming\"))~".
• Removing quotes may allow a broader search: (( _ convolutional coding coding program ) OR ( advanced communications of python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("_ convolutional coding coding program") OR ("advanced communications of python programming"))*.
