• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"systematic implementation in precoder program\") OR (\"using using python python programming\"))".
• Removing quotes may allow a broader search: (( systematic implementation in precoder program ) OR ( using using python python programming )).
• Adding a wildcard symbol may retrieve word variants: (("systematic implementation in precoder program") OR ("using using python python programming"))*.
