In this paper, feed-forward pre-equalization in conjunction with a PAM modulation scheme are proposed for use in wireless visible light communication (VLC) systems in order to enable the transmission of data rates >1 Gb/s. Simulation results demonstrate that simple few-tap feed-forward pre-equalization is able to remove the intersymbol interference caused by the limited link bandwidth of a line...
In this paper, we address the problem of choosing the right topology for a wireless power transfer (WPT) application to obtain maximum power transfer efficiency. We analyze the series and parallel resonant topologies used in inductively coupled links, derive the efficiency expressions and verify them experimentally using planar inductors built on a PCB. We compare and contrast the two topologies and...
A communication system plays an important role in SCADA system, and various communication media have been applied to meet the SCADA system's objective. Wireless communication becomes an attractive option as communication network in some cases, such as small amount of data communication for extremely remote substation, remote debugging temporarily for newly-built generation plants and backup communication...
The stripline fed 60GHz CP 2x4 patch array and LP grid array were designed in LTCC technology. The arrays with GCPW-stripline transitions were fabricated and measured in terms of the impedance matching performance and polarization characteristics. The wireless access advantage of the CP patch array over the LP grid array antenna is demonstrated.
