In this paper, we investigate a cooperative relay network where two users exchange messages through a full-duplex relay. A joint relay transmit-receive antenna selection and opportunistic source selection (RAS-OSS) strategy is proposed to improve the performance of the full-duplex relay network, when the roles of the antennas at the full-duplex relay are not predefined. Both of the amplify-and-forward...
Pilot design plays a key role in the channel estimation of pilot-assisted multiple-input multiple-output (MIMO) systems. Power allocation is a momentous issue in the pilot design. In the literature, pilot power allocation among transmit antennas has not been investigated. This paper explores this issue by introducing discriminatory treatment of different channel parameters. Generally, the large-scale...
A monopole plasma antenna for Wi-Fi application at 2.4 GHz was constructed using a commercially available fluorescent tube. The plasma antenna uses a fluorescent tube with length and diameter of 0.61 m and 0.025 m, respectively. The tube contains a mixture of argon and mercury vapor, which becomes conductive when sufficiently ionized into plasma state, allowing transmissions of radio frequency signal...
