Cooperative Game Theory for Distributed Spectrum Sharing
— There is a need for new spectrum access protocols that are opportunistic, flexible and efficient, yet fair. Game theory provides a framework for analyzing spectrum access, a ...

Optimal LLR Clipping Levels for Mixed Hard/Soft Output Detection
Abstract—Consider a communications system where the detector generates a mix of hard and soft outputs, which are then fed into a soft-input channel decoder. In such a setting, it...

High-throughput, reliable multicast without "crying babies" in wireless mesh networks
There are two primary challenges to supportinghigh-throughput, reliable multicast in wireless mesh networks (WMNs). The first is no different from unicast: wireless links are inhe...

Amplify-and-forward cooperation under interference-limited spatial reuse of the relay slot
1 . Cooperative transmission has emerged as an effective tool to deal with channel impairments. In this work we study the applicability of amplify-and-forward cooperative transmiss...
