摘要: A cognitive heterogeneous network with unreliable backhaul connections is studied in this paper. In system, a macro-base station connected to cloud transmits information multiple small cells via links. addition, acting as secondary transmitters send receiver by sharing the same spectrum primary users. Bernoulli process adopted model reliability. Selection combining protocol used at side maximize received signal-to-noise ratio. We investigate impacts of number small-cells, users well reliability on system performance, i.e., outage probability Rayleigh fading channels. Closed-form expressions are derived and asymptotic analysis also provided.
