Abstract :
As a next generation mobile satellite network, an integrated satellite and complementary ground component (CGC) network is recently considered in order to provide seamless, transparent and ubiquitous wireless coverage over the world. In this network, it is essential to reuse efficiently frequencies between satellite and CGC components under tolerable interference level. In this paper, we propose how the CGC can reuse satellite frequencies in an OFDMA based multi-beam mobile satellite system with frequency reuse factor 1. In our scheme, the CGC is operated via beam division multiple access (BDMA) for interference mitigation between satellite and CGC signals.
