In this paper we experimentally realized bidirectional optical wireless communication (OWC) link using four channel visible LED board exploiting wavelength division multiplexing (WDM) for the downlink and infrared LED for uplink. We achieved greater than 5 Gbit/s data rate at common indoor distance (1.5 to 4 m) for downlink and 1.5 Gbit/s for uplink using(More)
Different classes of communication network topologies and their representation in the form of adjacency matrix and its eigenvalues are presented. A self-organizing feature map neural network is used to map different classes of communication network topological patterns. The neural network simulation results are reported.
In this article we present a simple technique that utilizes the cross correlations between ECG signals and haemodynamic signals for the purpose of assessing signal quality and detecting artifacts in the arterial blood pressure (ABP) signal. The technique was tested using cases from a physician-annotated patient monitoring signal database from Beth(More)
One of the most vibrant and active " new " fields today is that of ad-hoc networks. In recent years, a variety of new routing protocols targeted specifically for ad-hoc networks have been developed. Current routing algorithms are not adequate to tackle the increasing complexity of such networks and it is not clear that any particular algorithm or class of(More)
We show practical feasibility of Long-Term Evolution (LTE) based indoor coverage using optical wireless communication, exploiting commercially available Light Emitting Diodes (LEDs). A common LTE-Advanced signal is distributed in downlink by a visible LED, and in uplink by infrared LED (IR-LED). We demonstrate the bidirectional transmission operating in(More)

The current study investigates the dynamic relationship between structural changes, real GDP per capita, energy consumption, trade openness, population density, and carbon dioxide (CO2) emissions within the EKC framework over a period 1971-2013. The study used the autoregressive distributed lagged (ARDL) approach to investigate the long-run relationship(More)
