Abstract:

Regularized zero-forcing (RZF) precoding can be used in multiple-beam mobile satellite communication (MSC) system downlink to combat interbeam-interference for high energy efficiency. We adopt the interference cancelation idea in approximate message passing (AMP) algorithm and propose an interference cancelation message passing (IC-MP) algorithm. To combine the virtues of both IC-MP and AMP, a hybrid message passing (H-MP) algorithm is also proposed. Simulation results show that H-MP has the best performance compared with IC-MP and AMP, and may even outperform the centralized RZF precoding.
