Distortion-Aware Beamforming for Integrated Sensing and Communication Systems
Radar and communication systems have historically operated as separate entities but have gradually evolved toward higher frequency bands, large antenna arrays, and compact hardware designs. This evolution has resulted in ... -
Analysis and design of Integrated optical biosensors with intermediate buffer layers
The objective of this thesis is to analyse photonic integrated biosensor. Photonic integrated biosensor are choosen for analysis as it is offering high sensitivity, miniaturization to nano scale and high stability. PIC ... -
Modeling and analysis of adaptive window controlled randomly arriving file transfers in Internets
The Internet carries predominantly elastic traffic generated by applications such as email, web transfers, and file transfers, and the bandwidth sharing between such sessions is controlled by the Transmission Control ... -
Non linear vibrations of stretched strings
The results obtained in this chapter can be summarized as follows. It is not possible to induce purely transverse oscillations since longitudinal and transverse oscillations are coupled together. However, if the order of ... -
PC. base interferometer for radio astronomy
5.1 Review As shown in the previous chapters through analytical, design, and experimental studies, the PC?based DAS is a very useful building block in radio interferometry. This has enabled the development of a PC?based ... -
Nonexponential decay of sound in rooms
(i) The above analysis of decay of sound in rectangular rooms under various boundary conditions shows that the overall decay is in general non?exponential because the normal modes corresponding to different angles of ... -
Studies on the role of spatial coherena in the lau phenomenon
The Laue effect is of fundamental importance in the domain of optical interference phenomena. In the Laue experiment, interference fringes are formed in the far field when an extended source illuminates two gratings placed ... -
Relative efficiencies of devanagari and tamil scripts for reading
This thesis is devoted primarily to some of the problems involved in reading with particular emphasis on Devanagari and Tamil scripts. Scripts are considered as codes and their performance examined on the basis of information ... -
Space- Time block codes with low maximum likelihood decoding complexity and large coding gain
Space-time block coding has been an extensively researched technique to combat multipath fading in multiple-input, multiple-output (MIMO) systems when the channel-state information is available at the receiver but not at ... -
Theoretical study of surface wave characteristics of a circular cyclindrical conductor coated with 2 graded dielectric layers embeoded in isotropic & anisotropic media
The study investigates a cylindrical conductor coated with two dielectric layers, both having radially varying dielectric constants, and the external medium being lossless, either: (a) Isotropic, or (b) Anisotropic The ... -
Non linear vibrations of stretched strings
The viscosity of pure Freon-12 and Freon-22 vapours and their mixtures has been determined by an oscillating disc viscometer at room temperature and pressure. The results agree well with the published data for the pure ... -

Intelligent Reflecting Surfaces for Wireless Communications: Low-Complexity Techniques and Performance Analysis
Intelligent reflecting surface (IRS), also referred to as reconfigurable intelligent surface (RIS), is an emerging technology aimed at dynamically controlling the propagation environment of next-generation wireless systems. ... -
Efficient Signal and Modulation Classification for High Mobility Wireless Communication System
The escalating demand for high-mobility applications, such as vehicle-to-everything (V2X) networks, high-speed rail, and internet of things (IoT), drives the evolution of sixth-generation (6G) wireless communication ... -
Diffusion approximation models for broadband integrated networks and their performance evaluation
In this thesis, we first consider the VBR video traffic modelling, then the reactive congestion control of VBR and BET traffic, and finally the optimal scheduling scheme for CBR traffic over the broadband integrated services ...
