Distributed beamforming and power allocation for cooperative networks. [PDF]
, 2008 Cooperative diversity systems rely on using relay nodes to relay copies of transmitted information to the destination such that each copy experiences different channel fading, hence increasing the diversity of the system.

Throughput Analysis of ALOHA with Cooperative Diversity [PDF]
IEEE Communications Letters, 2008 Cooperative transmissions emulate multi-antenna systems and can improve the quality of signal reception. In this paper, we propose and analyze a cross layer random access scheme, C-ALOHA, that enables cooperative transmissions in the context of ALOHA system.

Including Diversity Through Cooperation
Procedia Computer Science, 2012 AbstractIn this article we describe the experience of several Portuguese Higher Education Institutions (HEI) that in the midst of a legislative void regarding the inclusion of students with special education's needs, try to work their way into the inclusion of those students through cooperation.We will focus on how that cooperation came into being, the
