Linear network coded cooperation (LNCC) is a new technology that combines linear network coding and cooperative communication. LNCC can dramatically reduce system outage probability and hence increase spectrum efficiency. The outage performance considering path loss is essential for further system optimizations for LNCC, such as optimal power allocation and optimal relay selection. However, as far as we know, this issue still remains open. In this paper, we investigate the outage performance of a two-slot multiuser LNCC system in many-to-one communication mode. We fully consider the effect of pathloss in the process of theoretical analysis and theoretically derive the tight approximated outage probability of LNCC system. And the analytic results are verified by Monte Carlo simulations. Numerical results show that two-slot LNCC system with path loss is able to greatly improve the outage performance.
