Capacity of hybrid cognitive radio networks with distributed VAAs
(IEEE, 2010-09)
A cooperative hybrid cognitive radio (CR) network is proposed to simultaneously operate on a dedicated licensed band and a secondary band. The licensed band is used for communications between a base station (BS) and mobile ...
Diversity-multiplexing trade-off in coherent free-space optical systems with multiple receivers
(IEEE, 2010-12)
In this paper, from an information theory point of view, we investigate the performance of a coherent freespace optical (FSO) communication system with multiple receive apertures over atmospheric turbulence channels. Our ...
Spectrum trading for non-identical channel allocation in cognitive radio networks
(IEEE, 2011)
In this paper, we investigate spectrum trading via auction approach for cognitive radio networks. We consider a realistic valuation function in terms of different parameters for secondary users (SUs), and propose an efficient ...

Markov-based performance analysis of medium access in visible light communications
(IEEE, 2015)
Visible light communication (VLC) uses the illumination infrastructure to provide high speed wireless connectivity. VLC has recently emerged as a promising alternative/complementary technology to conventional radio-frequency ...
Adaptive unipolar MIMO-OFDM for visible light communications
(IEEE, 2019)
Unipolar orthogonal frequency division multiplexing (U-OFDM) appears as an attractive optical OFDM solution for emerging visible light communication (VLC) systems. This paper proposes spectral efficiency improvement for ...
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. ...
Colour gamut enhancement with remote light conversion mechanism
(IOP Publishing, 2018)
The backlight unit spectrum of liquid crystal displays (LCD) directly affects the colour gamut. With the invention of GaN based blue light emitting diodes (LED), phosphors and quantum dots (QD) have gained considerable ...
