Adaptive Amplify-and-Forward Cooperative Diversity using Phase Feedback
— Cooperative diversity obtains the spatial diversity gains created by sharing antennas of terminals in wireless networks. In this paper, adaptive amplify-and-forward (AF) cooper...

MIMO Cooperative Diversity in a Transmit Power Limited Environment
— This paper considers a fading relay channel where the total transmit power used is constrained to be equal to that of the standard single-hop channel. The relay channel used op...

Detecting Malicious Behavior in Cooperative Diversity
—We consider a cooperative diversity scheme where a relay cooperatively enhances communication between a source and destination. In cooperative diversity, due to lack of a mechan...

Relay-Assisted ARQ in Wireless Ad-Hoc Networks
— In this paper we study a simple protocol utilizing two-hop cooperative diversity augmented with “automatic repeat request” (ARQ) for multi-hop ad-hoc networks. This protoco...

A Stochastic Model for Misbehaving Relays in Cooperative Diversity
—Existing cooperative diversity protocols are designed with the inherent assumption that users exhibit cooperative behavior all the time. However, in a practical cooperative wire...
