Abstract
In OFDMA based MSS system, 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 area and minimizes the interference between adjacent beams in an OFDMA based mobile satellite communication. In addition, Simulation results show that it makes the received signal to noise ratio increased due to diversity gain from cyclic delayed multi-point transmitted signals. This performance gain could be achieved without any modification of a conventional Single-Input and Single-Output tranceiver, differently from the space-frequency transmit diversity scheme.
