Performance analysis of multiple-input multiple-output free-space optical systems with partially coherent Gaussian beams and finite-sized detectors
(SPIE, 2016)
Multiple-input multiple-output (MIMO) techniques are employed in free-space optical (FSO) links to mitigate the degrading effects of atmospheric turbulence. We consider a MIMO FSO system, which consists of a radial laser ...
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 ...
Next generation M2M cellular networks: challenges and practical considerations
(IEEE, 2015-09)
In this article we present the major challenges of future machine-to-machine (M2M) cellular networks such as spectrum scarcity, and support for a large number of low-power, lowcost devices. As an integral part of the future ...
Fast, secure, and remote multiboot of FPGAs
(2012-09)
The purpose of this thesis is to develop an efficient framework to implement secure FPGA-based (Field Programmable Gate Array) systems. An FPGA is a reconfigurable device that has the ability to adapt the hardware during ...
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 ...
P2P live scalable video streaming with ALTO service
(2012-10)
It has been measured that, as high as 80% of the average Internet traffic is now from peer-to-peer (P2P) applications, and upwards of 90% during peak hours. These results tell us that a significant portion of the traffic ...
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 ...
