Perhaps you should try some spelling variations:
"and convolutional coding coding program" » "and convolutional codes coding program" (Expand search), "and convolutional code coding program" (Expand search), "and convolutional long coding program" (Expand search), "and conventional coding coding program" (Expand search), "of convolutional coding coding program" (Expand search), "_ convolutional coding coding program" (Expand search), "and convolutional coding cloning program" (Expand search), "and convolutional coding loading program" (Expand search), "and convolutional coding cooling programs" (Expand search), "and convolutional coding decoding program" (Expand search), "and convolutional coding using program" (Expand search), "and convolutional coding canine program" (Expand search)
"pulse comparation on python programming" » "pulse comparison on python programming" (Expand search), "pulse propagation on python programming" (Expand search), "pulse compression on python programming" (Expand search), "pulse comparation of python programming" (Expand search), "pulse comparation and python programming" (Expand search), "pulse compactation on python programming" (Expand search), "pulse comparation in python programming" (Expand search), "pulse comparation _ python programming" (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: "((\"and convolutional coding coding program\") OR (\"pulse comparation on python programming\"))~".
• Removing quotes may allow a broader search: (( and convolutional coding coding program ) OR ( pulse comparation on python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("and convolutional coding coding program") OR ("pulse comparation on python programming"))*.
