Employing energy harvesting (EH) at the relay with simultaneous wireless information and power transfer is promising to prolong lifetime of energy-constrained relay networks. In this letter, considering multicarrier decode-and-forward (DF) relay network with time-switching (TS) based relaying, we investigate the optimization problem which jointly designs TS(More)
In this paper, considering the channel estimation error and the presence of co-channel interferences (CCIs), we analyze the performance of multiuser multiple-input multiple-output wireless systems employing transmit beamforming and maximum ratio combining (MIMO MRC). Exact closed-form cumulative distribution function expression of the(More)
To efficiently utilize the advantages of orthogonal-frequency-division-multiplexing (OFDM) and wireless relay techniques, we propose the resource allocation schemes with statistical quality-of-service (QoS) guarantees for the wireless OFDM amplify-and-forward (AF) relay system in this paper. Firstly, we formulate the resource allocation problems for the(More)

Simultaneous Wireless Information and Energy Transfer (SWIET) is a promising energy harvesting technique to power energy-constrained wireless nodes in wireless communications. In wireless relay networks, employing SWIET at the source-to-relay link, an energy-constrained relay node can harvest energy from the radio-frequency (RF) signals transmitted by a(More)
The robustness differences of multiuser maximum ratio combining (MRC), MIMO-MRC and optimum combining (OC) systems with imperfect channel state information are analyzed. Using the multiuser average capacity difference CDR with channel estimation error, the robustness of the three systems are illustrated in a flat Rayleigh fading channel with multiple(More)
