Considering a decode-and-forward relay network with multiple source-destination pairs, this paper proposes a two-phase relaying protocol, which enables the massive multiple-input multiple-output (MIMO) relay to simultaneously harvest wireless energy from multiple sources' information signals and multiple destinations' energy flows (EFs). Asymptotic expression of the harvested energy is derived when...
This paper proposes a new source and relay precoding design in a two-way MIMO relay network based on cyclic prefixed single carrier (CP-SC) transmission. The source precoding, relay precoding, and decision feedback equalization with noise-prediction (DFE-NP) receivers are jointly designed to minimize the sum-mean squared error (MSE) of the network. An iterative algorithm is proposed to optimize the...
