Generalized LED index modulation optical OFDM for MIMO visible light communications systems
(IEEE, 2016)
In this paper, we propose a generalized light emitting diode (LED) index modulation scheme for multiple input multiple output-orthogonal frequency division multiplexing (MIMO-OFDM) visible light communications (VLC) systems. ...
DCT-OFDM tabanlı görünür ışık haberleşmesi
(2016)
Visible light communication (VLC) is a short-range wireless transmission technique in which light emitting diodes (LEDs) are used as data transmitters. Because of non-coherent characteristics of LEDs, only intensity can ...
Performance analysis of MIMO NLOS UV communications over atmospheric turbulence channels
(IEEE, 2016)
Strong molecular and aerosol scattering in ultraviolet (UV) wavelengths enable the non-line-of-sight (NLOS) outdoor wireless connectivity which is attractive in many applications due to covertness and security. In the ...
Optimization and analysis of WLAN RF energy harvesting system architecture
(IEEE, 2016)
This paper presents the design, analysis and optimization of RF energy harvesting system for WLAN source operating at 2.4 GHz and 5.8 GHz. The system architecture comprises of RF WLAN source, wireless channel, an efficient ...
Two cantilever based sytem for viscosity and density monitoring
(IEEE, 2015)
Viscosity and density measurements in liquids in real-time is challenging. Previous MEMS based approaches use frequency sweeps for the purpose and those methods are slow and not real-time. We show that high precision ...
Link allocation for multiuser systems with hybrid RF/FSO backhaul: Delay-limited and delay-tolerant designs
(IEEE, 2016-05)
In this paper, we consider a cascaded radio frequency (RF) and hybrid RF/free space optical (FSO) system where several mobile users transmit their data over an RF link to a decode-and-forward relay node (e.g., a small cell ...
Patch antenna with slits at 8 GHz
(IEEE, 2016)
In this paper, a rectangular shaped patch antenna with two equal rectangular shaped slits on each side and one at the top has been demonstrated. By modifying the size and the shape of the initial antenna, a radiation ...
LiFi channel models: office, home, manufacturing cell
(IEEE, 2015-09)
Purpose Providing channel models which allow a fair comparison of different physical layer (PHY) High Rate PD Communications proposals submitted to TG7r1 in response to the Call for Proposals (CFP). ... Notice This document ...
On throughput-delay optimal access to storage clouds via load adaptive coding and chunking
(IEEE, 2016-08)
Recent literature including our past work provides analysis and solutions for using: 1) erasure coding; 2) parallelism; or 3) variable slicing/chunking (i.e., dividing an object of a specific size into a variable number ...
Optimal combiners in optical wireless systems with spatial diversity and pre-amplification
(IEEE, 2016)
We present analytical results on the operation of a pre-amplified optical wireless communication (OWC) system that also takes advantage of spatial diversity to improve its outage probability and average bit-error-rate (BER) ...
