Query: A Cooperative Network Coding Strategy for the Interference Relay Channel   In this paper, we study an interference relay network with a satellite as
relay. We propose a cooperative strategy based on physical layer network coding
and superposition modulation decoding for uni-directional communications among
users. The performance of our solution in terms of throughput is evaluated
through capacity analysis and simulations that include practical constraints
such as the lack of synchronization in time and frequency. We demonstrate
throughputs significantly larger than the classical time sharing case.
