Abstract:

In order to improve the energy consumption efficiency of the distributed antenna system, a model of the cooperative multipoint transmission (CoMP) system was established. The channel propagation model, the energy consumption evaluation index and the system coverage, and the relationship existed in the distance between base stations and system energy efficiency were analyzed as well. The expressions between the distance between the base station and energy consumption efficiency were derived. Simulation was performed by Monte Carlo method. It is shown that, with increase of the distance between base stations in CoMP systems, there appears a trend that the energy consumption per unit area appears from large to small and then gradually become large. Meanwhile, the absolute contribution that the growth of the unit area contributes to the energy consumption per unit area also is seen from large to small and then gradually becomes large. Furthermore, the impaction of the energy consumption decrease per unit area on the system Spectrum efficiency seems relatively low. The distributed antenna deployment strategy of the minimum energy consumption per unit area in CoMP systems is therefore developed.
