Diversity Combining of Signals with Different Modulation Levels in Cooperative Relay Networks
In digital cooperative relaying, signals from the source-destination and relay-destination links are combined at the destination to achieve spatial diversity. These signals do not ...

Cross-Layer Design with Adaptive Modulation: Delay, Rate, and Energy Tradeoffs
— We present a crosslayer framework for optimizing the performance of wireless networks as measured by applications or upper layer protocols. The approach combines adaptive modul...
