Perhaps you should try some spelling variations:
"joint rerererererererererereresourcessssss–channel coding" » "joint rerererererererererereresourcesssssss–channel coding" (Expand Search), "joint rererererererererererereresourcessssss–channel coding" (Expand Search)
"point source–channel coding" » "point sources–channel coding" (Expand Search), "point resource–channel coding" (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: "((\"joint rerererererererererereresourcessssss–channel coding\") OR (\"point source–channel coding\"))~".
• Removing quotes may allow a broader search: (( joint rerererererererererereresourcessssss–channel coding ) OR ( point source–channel coding ))~.
• Adding a wildcard symbol may retrieve word variants: (("joint rerererererererererereresourcessssss–channel coding") OR ("point source–channel coding"))*.
