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 ...
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 ...
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 ...
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) ...
Diversity-multiplexing tradeoff for log-normal fading channels
(IEEE, 2016-07)
Although there has been a growing interest on the study of diversity-multiplexing tradeoff (DMT), the existing works are mostly restricted to the outcomes reported for Rayleigh, Rician, and Nakagami fading channels. In ...
Adaptive free space optical communication system with multiple apertures
(2016)
In the current literature on free space optical (FSO) communication, typically open-loop designs are considered where the knowledge of channel state information is only available at the receiver. This is mostly favorable ...
Adaptive relay selection method for asynchronous amplify and forward cooperative communications
(IEEE, 2016)
In this paper, we propose a new adaptive relay selection method named as Adaptive Best Relay Assessment (ABRA) for cooperative communication with amplify and forward (AF) relaying. ABRA is based on two relay selection ...
