      • Risk Estimation Strategies for Speech Signal Denoising 

        Sadasivan, Jishnu
        In automatic speech recognition (ASR) systems, the recognition performance is severely affected by noise in the input speech signal [2]. One can improve the performance of ASR systems in noisy environments by denoising ...
      • Robust Nonparametric Sequential Distributed Spectrum Sensing under EMI and Fading 

        Sahasranand, K R (2018-07-16)
        Opportunistic use of unused spectrum could efficiently be carried out using the paradigm of Cognitive Radio (CR). A spectrum remains idle when the primary user (licensee) is not using it. The secondary nodes detect this ...
      • Robust Precoder And Transceiver Optimization In Multiuser Multi-Antenna Systems 

        Ubaidulla, P (2013-10-04)
        The research reported in this thesis is concerned with robust precoder and transceiver optimization in multiuser multi-antenna wireless communication systems in the presence of imperfect channel state information(CSI). ...
      • Robust Techniques Of Language Modeling For Spoken Language Identification 

        Basavaraja, S V (2009-07-23)
        Language Identification (LID) is the task of automatically identifying the language of speech signal uttered by an unknown speaker. An N language LID task is to classify an input speech utterance, spoken by an unknown ...
      • Robustness And Localization In Time-Varying Spectral Estimation 

        Viswanath, G (2012-11-23)
      • Role of Channel State Information in Adaptation in Current and Next Generation Wireless Systems 

        Kashyap, Salil (2017-11-24)
        Motivated by the increasing demand for higher data rates, coverage, and spectral efficiency, current and next generation wireless systems adapt transmission parameters and even who is being transmitted to, based on the ...
      • Role of Nonlocality and Counterfactuality in Quantum Cryptography 

        Akshatha Shenoy, H (2018-01-09)
        Quantum cryptography is arguably the most successfully applied area of quantum information theory. In this work, We invsetigate the role of quantum indistinguishability in random number generation, quantum temporal ...
      • Role of Power Control in Enhancing the Performance of Opportunistic Selection Schemes 

        Dewangan, Vikas Kumar
        Opportunistic selection reaps the benefits of multiuser diversity in many wireless applications. For example, it increases throughput of cellular networks, lifetime of wireless sensor networks, and improves diversity in ...
      • RSMA Architectures for Downlink Communication Systems 

        Rajashekhar
        Demand for the internet is increasing day by day, and the number of internet users is also growing drastically. Multiple access (MA) plays an important role in the fifth-generation (5G) and upcoming sixth-generation (6G) ...
      • Scheduling For Stable And Reliable Communication Over Multiaccess Channels And Degraded Broadcast Channels 

        Kalyanarama Sesha Sayee, KCV (2008-09-26)
        Information-theoretic arguments focus on modeling the reliability of information transmission, assuming availability of infinite data at sources, thus ignoring randomness in message generation times at the respective ...
      • Secret Key Generation in the Multiterminal Source Model : Communication and Other Aspects 

        Mukherjee, Manuj (2018-07-04)
        This dissertation is primarily concerned with the communication required to achieve secret key (SK) capacity in a multiterminal source model. The multiterminal source model introduced by Csiszár and Narayan consists of a ...
      • Secure Routing Schemes In Mobile Ad Hoc Networks 

        Prashant, Dixit Pratik (2011-09-09)
      • Sequential Controlled Sensing to Detect an Anomalous Process 

        Narayanaprasad, Karthik Periyapattana
        In this thesis, we study the problem of identifying an anomalous arm in a multi-armed bandit as quickly as possible, subject to an upper bound on the error probability. Also known as odd arm identification, this problem ...
      • Sequential Detection Based Cooperative Spectrum Sensing Algorithms For Cognitive Radio 

        Jayaprakasam, ArunKumar (2011-07-11)
        Cognitive radios are the radios which use spectrum licensed to other users. For this, they perform Radio Environment Analysis, identify the Spectral holes and then operate in those holes. We consider the problem of Spectrum ...
      • Sequential Transfer in Multi-Armed Bandits using Reward Samples 

        Rahul, N R
        We consider a sequential multi-task problem, where each task is modeled as a stochastic multi-armed bandit with K arms. We study the problem of transfer learning in this setting and propose algorithms based on UCB to ...
      • Shaped Superconducting Films For Electronic Functions 

        Narayana, T Badiri (2012-11-26)
      • SOI Based Integrated-Optic Microring Resonators for Biomedical Sensing Applications 

        Mangal, Nivesh (2018-02-23)
        Integrated Silicon Photonics has emerged as a powerful platform in the last two decades amongst high-bandwidth technologies, particularly since the adop- tion of CMOS compatible silicon-on-insulator(SOI) substrates. Microring ...
