Title
Spectrum usage efficiency of coordinated multi-point transmission in mobile satellite communications
Abstract
In a mobile satellite system based on orthogonal frequency division multiplexing technique, the beam planning with frequency reuse factor 1 may induce severe inter-beam interference due to the usage of the same subcarrier between user equipments of adjacent beams. In order to solve this problem, this paper shows a coordinated multi-point transmission scheme combined with cyclic delay diversity. The proposed scheme improves frequency usage efficiency in a beam boundary region and minimizes interference inter-beam interference in mobile satellite communications based on orthogonal frequency division multiplexing technique. In addition, simulation results show that it makes total system capacity increased due to the significant improved signal to interference and noise power ratio in beam edge users.
