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