The performance of user-cooperation in a multi-access network is compared to that of using a wireless relay. Using the total transmit and processing power consumed at all nodes as...

Abstract-- Most user cooperation protocols work in a timesharing manner, where each user transmits its own message and relays for the other at different segments of a time slot. We...
For a fading Gaussian multiple access channel with user cooperation, we obtain the optimal power allocation policies that maximize the rates achievable by block Markov superpositi...
Abstract— In this paper, we propose a novel distributed Interleaved Random Space-Time Code (IR-STC) designed for MultiSource Cooperation (MSC) employing various relaying techniqu...
— In this paper, we design and investigate a novel Interleave Division Multiplexing based Space-Time Code (IDM-STC) in the context of cooperative communications. We outline the p...
