- W4367486883 abstract "In this paper, we study underlay cognitive multihop networks where both power constraints including the maximum tolerable interference level at primary receivers and the maximum transmit power at secondary transmitters are taken into account. We obtain the exact and approximated closed-form expressions at high and low signal-to-noise ratio (SNR) regime for the system outage probability. Based on the approximated expressions, the optimization problem on relay locations are considered. Numerical results show that underlay multihop networks with optimal relay positions significantly outperform that with randomized or uniform relay positions." @default.
