Abstract

In this paper, we propose subcarrier suppressed transmission for OFDMA (Orthogonal Frequency Division Multiple Access) in order to improve frequency utilization efficiency of STICS (Satellite/Terrestrial Integrated Mobile Communication System), which shares the same frequency band between satellite and land mobile systems. In OFDMA introducing channel rotation scheme, the proposed scheme can achieve as similar multi-user performance as single user. By computer simulation, we show the interference suppression performance and clarify the improvement ratio of the total average spectral efficiency.
