Design space–time trellis-coded intercarrier interference parallel cancelation architectures for ofdm systems
(IEEE, 2017-05)
Space-time (ST) coding combined with orthogonal frequency-division multiplexing (OFDM) is a robust transmission system. However, ST-OFDM system performance may degrade because of the intercarrier interference (ICI) in ...
The impact of pulse shaping filters on OFDM-based visible light communications
(IEEE, 2017)
This paper discusses the impact of pulse shaping filter on the performance of orthogonal frequency division multiplexing (OFDM) based visible light communication (VLC) systems. Particularly, direct current biased optical ...

Performance of OFDM-based adaptive visible light communications
(IEEE, 2017)
In this paper, we investigate the performance of a direct current biased optical orthogonal frequency division multiplexing (DCO-OFDM) based adaptive transmission in the context of visible light communication (VLC). We ...
Centralized light access network (C-LiAN): a novel paradigm for next generation indoor VLC networks
(IEEE, 2017)
Visible light communication (VLC) builds upon the idea of using existing lighting infrastructure for wireless data transmission. In a conventional VLC network, each light fixture acts as an access point (AP) which are ...
eU-OFDM based multiple access for visible light communication networks
(IEEE, 2017)
In this paper, we propose a novel protocol for cooperative multiple access in visible light communication (VLC) networks. The proposed protocol exploits the features of enhanced unipolar orthogonal frequency division ...
Experimental investigation of the impact on TCP traffic by hidden video-tagged UDP traffic
(IEEE, 2017)
This paper investigates the impact of video-tagged UDP traffic on best-effort TCP traffic in an experimental setup with a novel observation approach. Our setup consists of three 802.11ac nodes in a hidden node topology, ...
Statistical modeling of propagation channels for Terahertz band
(IEEE, 2017)
Digital revolution and recent advances in telecommunications technology enable to design communication systems which operate within the regions close to the theoretical capacity limits. Ever-increasing demand for wireless ...
ViLDAR: a novel speed estimation system using visible light in vehicles
(IEEE, 2017)
In this paper, we introduce Visible Light Detection and Ranging (ViLDAR): a novel speed estimation system that utilizes visible light variation during a known time difference. The use of light emitting diodes (LED) in ...
Hardware division by small integer constants
(IEEE, 2017-12)
This article studies the design of custom circuits for division by a small positive constant. Such circuits can be useful for specific FPGA and ASIC applications. The first problem studied is the Euclidean division of an ...
