Partner Selection Based on IDMA Superposition Modulation in Cooperative Cellular Networks

This paper studies expression of outage probability and partner selection strategies for cooperative network based on IDMA superposition modulation. By changing existing outage gain matrix into a symmetric new one and applying Hungary and WLF algorithm, a centralized optimal and a distributed sub-optimal partner selection strategies are proposed for superposition modulation cooperative multiple access cellular network. Simulation results show that the two proposed partner selection strategies could reduce the average outage probability of the network effectively.
