Abstract :
In this paper, a novel transmitting scheme for multiple-input multiple-output (MIMO) satellite relay-based multi-user multi-beam communications is proposed. It is considered that multiple terrestrial relay nodes employ amplify-and-forward (A-F) relaying and intend to improve the reliability and spectral efficiency of satellite radio links. Zero forcing (ZF) and minimum mean square error (MMSE) signal detection techniques are employed, which have been well-established in terrestrial wireless communication systems. Numerical results are provided to quantify the performance gain of the proposed system configuration in terms of the bit-error-rate (BER) and the channel capacity.
