Summary: 118 IEEE TRANSACTIONS ON WIRELESS COMMUNICATIONS, VOL. 7, NO. 1, JANUARY 2008
Selection Cooperation in
Multi-Source Cooperative Networks
Elzbieta Beres and Raviraj Adve
Abstract-- In a cooperative network with multiple potential
relays and multiple simultaneous transmissions, we present
selection cooperation wherein each source pairs with a single
"best" relay. We analyze the outage probability of a simple and
completely distributed selection scheme, requiring some feedback
but no centralization, and show that it outperforms distributed
space-time codes for networks with more than three relaying
nodes. These gains are due to the more efficient use of power
in networks using selection. We suggest two other more complex
selection schemes based on increasing system intelligence and
centralization, and show that for smaller network sizes their
performance improvement over the simple selection scheme is
not significant.
Index Terms-- Cooperative diversity, decode-and-forward, dis-
tributed space-time codes, outage probability, selection, user
cooperation.
