FIR System Identification Using Higher Order Cumulants -A Generalized Approach
(Indian Institute of Science, 2010-01-12)
The thesis presents algorithms based on a linear algebraic solution for the identification of the parameters of the FIR system using only higher order statistics when only the output of the system corrupted by additive ...
Interference Management For Vector Gaussian Multiple Access Channels
(2010-06-03)
In this thesis, we consider a vector Gaussian multiple access channel (MAC) with users demanding reliable communication at specific (Shannon-theoretic) rates. The objective is to assign vectors and powers to these users ...
Providing QoS To Real-time And Data Applications In 3G Wireless Systems
(2010-07-29)
In this thesis we address the problem of providing end-to-end quality of service (QoS) to real-time and data connections in a third generation (3G) cellular network based on the Universal Mobile Telecommunication System ...
Errors In Delay Differentiation In Statistical Multiplexing
(2010-03-03)
Different applications of communication networks have different requirements that depend on the type of application. We consider the problem of differentiating between delay-sensitive applications based on their average ...
Linear Network Coding For Wireline And Wireless Networks
(2010-02-10)
Network Coding is a technique which looks beyond traditional store-and-forward approach followed by routers and switches in communication networks, and as an extension introduces maps termed as ‘local encoding kernels’ and ...
Relay Selection for Geographical Forwarding in Sleep-Wake Cycling Wireless Sensor Networks
(2018-04-11)
Advances in wireless communication and microelectronics have led to the development of low-power compact sensor nodes (popularly called motes) that are capable of sensing, computing, and communication. A large number of ...
Lattice Codes for Secure Communication and Secret Key Generation
(2018-05-22)
In this work, we study two problems in information-theoretic security. Firstly, we study a wireless network where two nodes want to securely exchange messages via an honest-but-curious bidirectional relay. There is no ...
Low-Complexity Receiver Algorithms in Large-Scale Multiuser MIMO Systems and Generalized Spatial Modulation
(2018-04-18)
Multi-antenna wireless systems have become very popular due to their theoretically predicted higher spectral efficiencies and improved performance compared to single-antenna systems. Large-scale multiple-input multiple-output ...
Variability Aware Device Modeling and Circuit Design in 45nm Analog CMOS Technology
(2018-05-10)
Process variability is a major challenge for the design of nano scale MOSFETs due to fundamental physical limits as well as process control limitations. As the size of the devices is scales down to improve performance, the ...
Fully Integrated CMOS Transmitter and Power Amplifier for Software-Defined Radios and Cognitive Radios
(2018-05-18)
Software Defined Radios (SDRs) and Cognitive Radios (CRs) pave the way for next-generation radio technology. They promise versatility, flexibility and cognition which can revolutionize communications systems. However they ...
