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