The problem of cell sites planning in a given service area in LTE cellular networks is studied in this paper, the optimization objective of which is to minimize the power consumption of both users and cell sites under the constraint of cell load balancing. Non-uniform traffic distributions across the entire service area are considered. An efficient(More)
In this paper, the outage performance of a free-space optical (FSO) communication system with parallel all-optical relays is investigated by employing the photon counting methodology. Initially, a composite channel model is considered which includes atmospheric loss, pointing error and weak atmospheric turbulence. To show the impacts of the channel state(More)
Multi-input multi-output (MIMO) technique is attractive for visible light communication (VLC), which exploits the high signal-to-noise ratio (SNR) of a single channel to overcome the capacity limitation due to the small modulation bandwidth of the light emitting diode. This paper establishes a MIMO VLC system under the non-negativity, peak power and(More)
The problem is to obtain the optimal number of base stations (BSs) and their locations on minimized power consumption with requirements of coverage rate and cell load. In this paper, we propose a mathematical model of evaluation index for cell planning and identify the optimization problem. The system model characterizes the total power consumption of(More)
