| Abstract(in English) | We proposed the multi-satellite/multi-beam system with single frequency reuse applied Multi Input Multi Output (MIMO) techniques for achieving high capacity. In this system, received time asynchronous signals cause serious problems with channel estimation errors and degradation of equalization performance. In this paper, we clarify appropriate channel estimation and demultiplexing schemes for time asynchronous channels and also appropriate length of unique word (UW) and a coding rate of a forward error correct (FEC) in a typical transmission condition. Finally, we evaluate performance of the proposed scheme compared with conventional single satellite/multi-beam system with no frequency reuse. |
