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 ... -
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 ... -
Magnitude and wrap-phase OFDM for MIMO visible light communication systems
(IEEE, 2021-07)Generalized light emitting diode (LED) index modulation (GLIM) has been proposed as an effective multiple-input multiple-output (MIMO) orthogonal frequency division multiplexing (OFDM) scheme for visible light communications ... -
Multi-resampling doppler compensation in cooperative underwater OFDM systems
(IEEE, 2013)We consider a multi-carrier cooperative underwater acoustic communication (UWAC) system and investigate the Doppler scaling problem arising due to the motion of different nodes. Specifically, we assume an orthogonal frequency ... -
A simulation study of cooperative underwater acoustic communication
(2012-08)Cooperative communication promises significant performance gains in terms of link reliability, spectral efficiency, system capacity, and transmission range. Due to its indisputable advantages for high-speed underwater ...
