To support the unrelenting demand of services with gigabit data rates in indoor scenarios, a dense heterogeneous small cell network (HSCN) is presented as a promising paradigm for the fifth generation system. In this paper, the coverage probability for the downlink HSCN with three cell association methods, namely the nearest association, the N-th nearest association and the maximum received power...
Characterizing user access methods in heterogeneous cloud radio access networks (H-CRANs)is critical for performance optimization. Different from the user access in cloud radio access networks, the inter-tier interference from macro base station has a great impact on user access in H-CRANs. In this paper, after considering the inter-tier interference, the ergodic rates of downlink H- CRANs for two...
For the purpose of developing the feature of ternary quantum-dot cellular automata (QCA), the simulation algorithm which is directed to its semiclassical model was compiled, then the simulations about three simple ternary QCA devices have been achieved by virtue of Matlab, the results confirm that these structure's behavior and physical truth accord perfectly. The simulations show that the behavior...
