1.8-Gb/s WDM visible light communication over 50-meter outdoor free space transmission employing CAP modulation and receiver diversity technology

We experimentally demonstrate a WDM VLC system employing CAP modulation and receiver diversity technology. The record aggregate data rate of 1.8Gb/s with the BER less than 3.8×10-3 is successfully achieved over 50-m outdoor transmission.

A greedy algorithm in WSNs for maximum network lifetime and communication reliability

A wireless sensor network (WSN) usually operates in an unreliable wireless environment with energy constraint. Many researchers are primarily interested in energy awareness and communicationreliability of WSNs to maximize network lifetime. However, dealing with the conflicting problems of improving energy efficiency…

A Unified Approach to Universal Prediction: Generalized Upper and Lower Bounds

We study sequential prediction of real-valued, arbitrary, and unknown sequences under the squared error loss as well as the best parametric predictor out of a large, continuous class of predictors. Inspired by recent results from computational learning theory, we refrain…

PT-symmetry of multimode waveguides: A tool for multichannel communication

The idea of Parity-Time symmetry is to exploit the special eigenvalues of coupled modes experiencing a map of balanced gain and losses. We consider multimode waveguides with transverse PT-symmetry, hence we have N parallel stripe pairs (one gain stripe and…

SCB: Store-Carry-Broadcast Scheme for Message Dissemination in Sparse VANET

To take on challenges of communication in sparse VANET, we propose a Store-Carry-Broadcast (SCB) scheme to assist message dissemination by broadcasting over a specific road segment instead of a single vehicle. In the SCB scheme, an opposite vehicle helps to…
