Coding For Wireless Relay Networks And Mutiple Access Channels
(2011-07-12)This thesis addresses the design of low-complexity coding schemes for wireless relay networks and multiple access channels. The first part of the thesis is on wireless relay networks and the second part is on multiple ... -
Constellation Constrained Capacity For Two-User Broadcast Channels
(2011-07-12)A Broadcast Channel is a communication path between a single source and two or more receivers or users. The source intends to communicate independent information to the users. A particular case of interest is the Gaussian ... -
Cooperative Communication In Store And Forward Wireless Networks Using Rateless Codes
(2013-08-30)In this thesis, we consider a cooperative relay-assisted communication system that uses rateless codes. When multiple relays are present, the relay with the highest channel gain to the source is the first to successfully ... -
Low Power Receiver Architecture And Algorithms For Low Data Rate Wireless Personal Area Networks
(2013-09-03)Sensor nodes in a sensor network is power constrained. Transceiver electronics of a node in sensor network consume a good share of total power consumed in the node. The thesis proposes receiver architecture and algorithms ... -
A Low-Complexity Intrusion Detection Algorithm For Surveillance Using PIR Sensors In A Wireless Sensor Network
(2011-07-12)A Wireless Sensor Network (WSN) is a dense network of autonomous devices (or motes) with sensors that cooperatively monitor some physical or environmental conditions. These devices are resource constrained -limited memory, ... -
MDCT Domain Enhancements For Audio Processing
(2011-05-10)Modified discrete cosine transform (MDCT) derived from DCT IV has emerged as the most suitable choice for transform domain audio coding applications due to its time domain alias cancellation property and de-correlation ... -
Nonlinear Processing Of EEG and HRV Signals For The Study Of Physiological And Pathological States
(2013-04-26)Physiological signals, electroencephalogram (EEG) and heart rate variability (HRV), are generated by complex self-regulating systems. These signals are extremely inhomogeneous and nonstationary, and fluctuate in an irregular ... -
On The Fourier Transform Approach To Quantum Error Control
(2013-10-07)Quantum mechanics is the physics of the very small. Quantum computers are devices that utilize the power of quantum mechanics for their computational primitives. Associated to each quantum system is an abstract space known ... -
Optimum Event Detection In Wireless Sensor Networks
(2013-06-12)We investigate sequential event detection problems arising in Wireless Sensor Networks (WSNs). A number of battery–powered sensor nodes of the same sensing modality are deployed in a region of interest(ROI). By an event ... -
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). ... -
Sequential Detection Based Cooperative Spectrum Sensing Algorithms For Cognitive Radio
(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 ... -
Techniques For Low Power Motion Estimation In Video Encoders
(2013-02-12)This thesis looks at hardware algorithms that help reduce dynamic power dissipation in video encoder applications. Computational complexity of motion estimation and the data traffic between external memory and the video ... -
