Abstract
In cooperative communications, relay usually forwards a full information of source data as received. Unlike this approach, this paper proposes a new relaying scheme based on multi-layered superposition coding with multiple antennas which forwards only partial information of superposed layer(s) on top of basic layer(s) of the source data. Fast forwarding of the partial information results in an increase in overall capacity. Simulation results are presented to show the superiority of the proposed scheme over full information relaying and direct transmission.
