  • Bose, Sayak; Pal, Siddharth; Natarajan, Bala; Scoglio, Caterina M.; Das, Sanjoy; Schulz, Noel N. (2012-10-08)
    In power system reconfiguration, the status (ON/OFF) of switches are optimized such that maximum power is delivered to loads after the occurrence of a fault. The optimized reconfiguration is achieved by prioritizing power ...
  • Gnanapandithan, N.; Natarajan, Bala (Institute of Electrical and Electronics Engineers, 2010-08-10)
    In this paper, we study the performance of a decentralized sensor network in the presence of correlated additive Gaussian noise. We propose a parallel genetic algorithm approach to simultaneously optimize both the fusion ...
  • Hijazi, S. L.; Best, A. J.; Natarajan, Bala; Das, Sanjoy (Institute of Electrical and Electronics Engineers, 2010-08-10)
    In this paper, we present a novel multiuser detection (MUD) technique based on ant colony optimization (ACO), for synchronous multi-carrier code division multiple access (MC-CDMA) systems. ACO algorithms are based on the ...
  • Roseveare, Nicholas J.; Natarajan, Bala (2013-04-09)
    We consider a wireless sensor network (WSN) tasked with tracking a process using a set of distributed nodes. Here multiple remote sensor nodes estimate the physical process (viz., a moving object) and transmit quantized ...
  • Natarajan, Bala; Das, Sanjoy; Stevens, D. (Institute of Electrical and Electronics Engineers, 2010-08-10)
    This paper proposes a novel evolutionary approach to spreading code design in direct sequence code division multiple access (DS-CDMA). Specifically, a multiobjective evolutionary algorithm (EA) is used to generate complex ...
  • Nassar, C.R.; Natarajan, Bala; Shattil, S. (Institute of Electrical and Electronics Engineers, 2010-07-15)
    This paper introduces a new scheme for spread spectrum multiple access. Like MC-CDMA, this scheme accomplishes spectral spreading by transmission of identical data over N carriers simultaneously. However, unlike any existing ...
  • Akter, Lutfa; Natarajan, Bala (Institute of Electrical and Electronics Engineers, 2010-07-14)
    In this paper, we consider an Erlangian process model for secondary user (SU) traffic in a cognitive radio network (CRN). Unlike prior efforts that focused on Poisson traffic models, the model captures bulk arrival and ...
  • Akter, Lutfa; Natarajan, Bala (IEEE, 2010-07-07)
    We consider a multi-channel cognitive radio network (CRN) where multiple secondary users share a single channel and multiple channels are simultaneously used by a single secondary user (SU) to satisfy their rate requirements. ...
  • Thippavajjula, V.; Natarajan, Bala (Institute of Electrical and Electronics Engineers, 2010-08-10)
    In this paper, we analyze the uplink performance of an asynchronous carrier interferometry/MC-CDMA, with nonlinear parallel and serial interference cancellation techniques. Specifically, we employ the new variant of parallel ...
  • Kopparthi, S.; Natarajan, Bala (Institute of Electrical and Electronics Engineers, 2010-12-15)
    In most previous studies, distributed sensor networks are typically assumed to be memory less. In this paper, we consider a distributed sensor network with feedback at both the sensor level as well as at the fusion center. ...
  • Natarajan, Bala; Nassar, C.R.; Shattil, S. (Institute of Electrical and Electronics Engineers, 2010-08-10)
    This paper introduces a novel TDMA scheme that provides enhanced throughput by employing carrier interferometry pulse shapes (CI pulse shapes). At the transmitter, CI pulse shapes are created from the superposition of N ...
  • Krishnan, Rajet; Natarajan, Bala; Warren, Steven (2010-09-23)
    Corruption of photopleythysmograms (PPGs) by motion artifacts has been a serious obstacle to the reliable use of pulse oximeters for real-time, continuous state-of-health monitoring. In this paper, we propose an automated, ...
  • Krenzel, Devon; Warren, Steven; Li, Kejia; Natarajan, Bala; Singh, Gurdip (IEEE, 2013-09-18)
    Accidental slips and falls due to decreased strength and stability are a concern for the elderly. A method to detect and ideally predict these falls can reduce their occurrence and allow these individuals to regain a degree ...
