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 transceiver design in a cognitive radio networks is studied, where all nodes are deployed with multiple antennas. A primary point-to-point MIMO link is authorized to utilize the spectrum. Ignoring the secondary users, the primary transmitter and receiver are designed based on the traditional singular value decomposition method. The secondary users(More)
