Research on Coded Cooperative Strategy in Satellite Communications

Abstract:

Aiming at the satellite mobile communication, the cooperative communication technology is applied to the forward downlink in this paper, and one scheme with two satellites based on the coded cooperative which used the Alamouti space time block code is presented. Simulation results show the coded cooperative strategy can obtain better performance than the traditional uncoded systems, which is lower than the MIMO system with two transmit antennas and one receive antenna based on the Alamouti code, but the power of the terminal was decreased. It has the advantage in communication range and low complex mobile terminal, which has a certain application prospects in satellite mobile communications in the future.
