Adaptive DCO-OFDM for underwater visible light communications
(IEEE, 2019-04)
Visible light communication (VLC) has been introduced as a complementary technology to acoustic communications for underwater applications. Underwater VLC can achieve much higher data rates sufficiently high for real-time ...
Multicarrier HF communications with amplify-and-forward relaying
(IEEE, 2011)
High-frequency (HF) radio communication has been recognized as the primary means for long-range wireless communications since the advent of radio. With its unique features, HF communication continues to be used for a wide ...
Adaptive MIMO FSO communication systems with spatial mode switching
(IEEE, 2018-08)
In this paper, we propose an adaptive multiple-input multiple-output (MIMO) free-space optical (FSO) system with dynamic adaptation between spatial modes of operation. The proposed adaptive system supports three MIMO modes. ...
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 ...

Cooperative BICM-OFDM systems for frequency-selective relay channels
(IEEE, 2011)
In this paper, we consider a cooperative multi-carrier multi-relay system over frequency-selective fading channels. Specifically, we adopt the orthogonal frequency division multiplexing (OFDM) with bit-interleaved ...
Outage analysis of q-duplex RF/FSO relaying
(IEEE, 2015)
In this paper, we propose and analyze a novel q-duplex radio frequency/free space optical (RF/FSO) relaying protocol for a mixed RF and hybrid RF/FSO communication system. In our scheme, several mobile users transmit their ...
On the benefits of cooperation via power control in OFDM-based visible light communication systems
(IEEE, 2014)
In this paper, the performance of a visible light communication (VLC) network exploiting power control is considered. The achievable rate region of two VLC communication pairs is characterized. The system employs optical ...
Ray tracing based channel modeling for visible light communications

Bu bildiride, Zemax 13 yazılımı aracılığı ile görünür ışık haberleşmesi (visible light communication, VLC) kanalları karakterize edilecektir. Yaklaşımımızda, ölçülerini tanımlayacağımız iç mekân ortamı üçboyutlu olarak ...
Relay selection for cooperative underwater acoustic communication systems
(IEEE, 2012)
In this paper, we consider a multi-carrier and multi-relay underwater acoustic communication (UWAC) system and investigate the relay selection problem. Our channel model is built on an aggregation of both large-scale path ...
