Zero Forcing Processing in Two Hop Networks with Multiple Source, Relay and Destination Nodes

In this paper, we consider two hop networks with multiple source, relay and destination nodes. In particular, we investigate systems with different processing capabilities at the relay and destination nodes. We derive new closed-form outage probability expressions when zero forcing processing is used at the i) relay, ii) relay and destination and iii) destination nodes only. Our results indicate significant decreases in outage probability for certain node configurations. We confirm our results through comparison with Monte Carlo simulations.
