Perhaps you should try some spelling variations:
"using convolutional code coding program" » "using convolutional codes coding program" (Expand search), "using convolutional and coding program" (Expand search), "using convolucional cnn coding program" (Expand search), "using convolutional code cloning program" (Expand search), "using convolutional code loading program" (Expand search), "using convolutional code cooling programs" (Expand search), "using convolutional code codigo program" (Expand search), "using convolutional code according program" (Expand search)
"using positioning in coding program" » "in positioning in coding program" (Expand search), "using positional in coding program" (Expand search), "business positioning in coding program" (Expand search), "using positioning of coding program" (Expand search), "using positioning in cloning program" (Expand search), "using positioning in loading program" (Expand search), "using positioning in cooling programs" (Expand search), "using positioning on coding program" (Expand search), "using positioning in decoding program" (Expand search), "using positioning non coding 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: "((\"using positioning in coding program\") OR (\"using convolutional code coding program\"))~".
• Removing quotes may allow a broader search: (( using positioning in coding program ) OR ( using convolutional code coding program ))~.
• Adding a wildcard symbol may retrieve word variants: (("using positioning in coding program") OR ("using convolutional code coding program"))*.
