Energy-efficient relay cooperation for lifetime maximization
We study energy-efficient power allocation among relays for lifetime maximization in a dual-hop relay network operated by amplify-and-forward relays with battery limitations. Power allocation algorithms are proposed for three different scenarios. First, we study the relay cooperation case where all …

Precoder Design for Cooperative Cognitive Radio Systems
… communication in recent years. In this thesis, optimal transmission strategies at the source and relay nodes in cooperative underlay CR systems assumption are studied with an aim of achieving maximum possible throughput for the secondary system for two different scenarios: one with multiple …
