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 decoding program" » "_ convolutional codes decoding program" (Expand search), "_ convolutional code decoding program" (Expand search), "_ convolutional long decoding program" (Expand search), "_ convolutional coding welcoming program" (Expand search), "_ convolutional coding deworming program" (Expand search), "_ convolutional coding feeding program" (Expand search), "_ convolutional encoding decoding program" (Expand search), "_ convolutional reading decoding program" (Expand search), "_ convolutional joint decoding 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 decoding program\") OR (\"advanced communications of python programming\"))~".
• Removing quotes may allow a broader search: (( _ convolutional coding decoding program ) OR ( advanced communications of python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("_ convolutional coding decoding program") OR ("advanced communications of python programming"))*.
