A distributed coding protocol for wireless relay networks

Cooperative diversity is a transmission technique, where multiple users pool their resources to form a virtual antenna array that obtain spatial diversity. We evaluate the performance of coded cooperation with multiple relays in Reyleigh fading channels. The closed-form expressions with multiple relays are derived in this work. Our numerical results show that the new coded cooperation method can achieve a noticeable gain over non-cooperative networks. Moreover, the analytical upper bounds are validated with simulation results.
