Partial Power and Rate Adaptation for MQAM/OFDM Systems under CFO
(IEEE, 2014)
In this paper a new partial power and rate adaptation scheme for orthogonal frequency division multiplexing (OFDM) systems is proposed in the presence of carrier frequency offset (CFO). The conventional adaptive scheme is ...
Sparse channel estimation for OFDM-based underwater cooperative systems with amplify-and-forward relaying
(IEEE Computer Society, 2014)
This paper is concerned with a challenging problem of channel estimation for amplify-and-forward cooperative relay based orthogonal frequency division multiplexing (OFDM) systems in the presence of sparse underwater acoustic ...
Orthogonal frequency division multiplexing with index modulation in the presence of high mobility
(2013)
In this paper a novel orthogonal frequency division multiplexing (OFDM) scheme which is called OFDM with index modulation (OFDM-IM) is proposed for frequency-selective fading channels in the presence of high mobility. In ...
Reliable two-path successive relaying
(2013)
Emerging two-path successive relaying protocols generally rely on error-free source-relay channels and/or interference-free inter-relay channels to achieve high-rate and full-diversity. In this paper by removing these ...
Channel estimation in underwater cooperative OFDM system with amplify-and-forward relaying
(IEEE, 2012)
This paper is concerned with a challenging problem of channel estimation for amplify-and-forward cooperative relay based orthogonal frequency division multiplexing (OFDM) systems in the presence of sparse underwater acoustic ...
Power Control-Based Multi-User Li-Fi Using A Compound Eye Transmitter
(IEEE, 2015)
In visible light communications (VLC) the transmitted signal is non-negative and real valued and these characteristics constrain the signal space and provide new challenges for waveform design in a multi-user system. In ...
Super-orthogonal trellis-coded spatial modulation
(Inst Engineering Technology-IET, 2012)
Spatial modulation (SM) which employs the indices of multiple transmit antennas to transmit information in addition to the conventional M-ary signal constellations is a novel transmission technique that has been proposed ...
Special issue on broadband mobile communications at very high speeds
(Springer International Publishing Ag, 2012)
[Abstract Not Available]
Relay-Aided Secure Broadcasting for VLC
(IEEE, 2018)
A visible light communication (VLC) broadcast channel is considered in which a transmitter communicates with two receivers in the presence of an external eavesdropper. Trusted cooperative half-duplex relays are deployed ...
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. ...
