In this paper, the design and analysis of a new bandwidth-efficient signaling method over the bandlimited intensity-modulated direct-detection (IM/DD) channel is presented. The channel can be modeled as a bandlimited channel with nonnegative input and additive white Gaussian noise (AWGN). Due to the nonnegativity constraint, standard methods for coherent(More)
This paper investigates the capacity of a channel in which information is conveyed by the timing of consecutive packets passing through a queue with independent and identically distributed service times. Such timing channels are commonly studied under the assumption of a work-conserving queue. In contrast, this paper studies the case of a bufferless queue(More)

Fast changing topologies, unpredictable network loads, potential broadcast storms, and identity-location conflation problems in IP networks all impose challenges on connected car system design. Prior approaches have proposed smart flooding using location information, carry and forward, and GeoServer assisted algorithms. Due to the complexity and overhead(More)

There has been a considerable interest in quantifying the influence that one node exerts on another in a social network. Using directed information, we study the problem for a simple, two-node network that models two users in a Twitter network in which one user (Alice) influences the other user (Bob) through her tweets. Under this setup, we relate the(More)

—We investigate the effect of polarization-dependent loss (PDL) on the constant modulus algorithm (CMA) in 4-QAM and 16-QAM polarization multiplexed (PolMux) systems with varying number of fiber spans and different PDL values. To quantify this effect, outage probability is introduced as the probability of having a signal-to-noise ratio (SNR) degradation(More)
