Perhaps you should try some spelling variations:
"using convolutional coding coding program" » "using convolutional codes coding program" (Expand search), "using convolutional code coding program" (Expand search), "using convolutional long coding program" (Expand search), "using convolutional coding cloning program" (Expand search), "using convolutional coding loading program" (Expand search), "using convolutional coding cooling programs" (Expand search), "using convolutional coding decoding program" (Expand search), "using convolutional coding using program" (Expand search), "using convolutional coding canine program" (Expand search)
"data compression on coding program" » "data compression of coding program" (Expand search), "data compression in coding program" (Expand search), "data compression and coding program" (Expand search), "data compression on cloning program" (Expand search), "data compression on loading program" (Expand search), "data compression on cooling programs" (Expand search), "data compression non coding program" (Expand search)

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

• Performing a fuzzy search may retrieve terms with similar spellings: (("data compression on coding program") OR ("using convolutional coding coding program"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"data compression on coding program\") OR (\"using convolutional coding coding program\"))".
• Removing quotes may allow a broader search: (( data compression on coding program ) OR ( using convolutional coding coding program )).
• Adding a wildcard symbol may retrieve word variants: (("data compression on coding program") OR ("using convolutional coding coding program"))*.
