Cooperation in wideband channels
Ramy Abdallah Tannious, Aria Nosratinia · 2005
In this paper we address cooperation in wideband channels. We first discuss a straight forward extension of existing cooperation protocols. The outage expressions for the wideband cooperation are cataloged. We also consider the case where a limited amount of channel state feedback is allowed. We explore the different ways that this side information can be used to improve the performance of user cooperation.
