Resource Management In Celluar And Mobile Opportunistic Networks
(2015-01-07)In this thesis we study several resource management problems in two classes of wireless networks. The thesis is in two parts, the first being concerned with game theoretic approaches for cellular networks, and the second ... -
Revealing Disocclusions in Temporal View Synthesis
We consider the problem of temporal view synthesis, where the goal is to predict a future video frame from the past frames using knowledge of the depth and relative camera motion. The problem has applications in frame rate ... -
Reverse Channel Training in Multiple Antenna Time Division Duplex Systems
(2018-04-02)Multiple-Input Multiple-Output (MIMO) communication using multiple antennas has received significant attention in recent years, both in the academia and industry, as they offer additional spatial dimensions for high-rate ... -
Risk Estimation Strategies for Speech Signal Denoising
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
(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
(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
(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�
Many practical signals, such as speech, music, etc., are inherently time?varying, but most of the analysis models used in applications such as coding, recognition, synthesis, etc., are based on the quasi?stationary assumption. ... -
