Abstract

Due to the prohibition of instantaneous channel state information (CSI) at the satellite gateway resulting from the long round trip time, current cooperative MIMO techniques for the integrated mobile satellite service system focus on diversity transmission. In this work, partial precoding is proposed, which can solve this problem to some degree. In this method, the satellite retains the conventional transmission without any knowledge of the CSI, while linear precoding is executed at the complementary ground component based on the CSI of the satellite and terrestrial channel. Both perfect and imperfect CSIT are investigated, and corresponding transceiver designs are proposed. Simulation results demonstrate that CSIT of the satellite channel can help dramatically improve system performance.
