Aperture averaging in multiple-input single-output free-space optical systems
(SPIE, 2015-06)
Multiple-input single-output systems are employed in free-space optical links to mitigate the degrading effects of atmospheric turbulence. We formulate the power scintillation as a function of transmitter and receiver ...
Emerging optical wireless communications-advances and challenges
(IEEE, 2015-09)
New data services and applications are emerging continuously and enhancing the mobile broadband experience. The ability to cope with these varied and sophisticated services and applications will be a key success factor for ...
On the performance of SC-FDE schemes with decision feedback equalizer for visible light communications
(IEEE, 2015)
In this paper, we investigate the two single carrier frequency domain equalization (SC-FDE) techniques, namely on-off keying single carrier frequency domain equalization (OOK-SC-FDE) and decomposed quadrature optical ...
Mixed RF and hybrid RF/FSO relaying
(IEEE, 2015)
In this paper, we consider a mixed RF and hybrid RF/FSO system where several mobile users transmit their data over an RF link to a relay node (e.g. a small cell base station) and the relay forwards the information to a ...
TG7r1 channel model document for high rate PD communications
(2015-09-10)
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 ...

(IEEE, 2015-11-14)
The LiFi channels developed by Prof. Murat Uysal and Mr. Miramirkhani were selected as the "LiFi Reference Channel Models" by the IEEE 802.15.7r Task Group during the IEEE's latest meeting held in Bangkok, Thailand, in ...
Guest editorial: Optical wireless communications
(IEEE, 2015-09)
Optical wireless communication (OWC) systems provide many advantages over radio frequency (RF) wireless technologies in some scenarios, including significantly higher data rates and a large amount of available license-free ...
Signal to noise ratio optimization for a CMUT based medical ultrasound imaging system
(IEEE, 2015)
CMUTs offers key performance benefits compared to their piezoelectric counterparts. However, CMUTs are not widely adopted in commercial ultrasound imaging systems due to low signal to noise ratio (SNR) in the obtained ...
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 ...
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 ...
