Optimal Control Problems In Communication Networks With Information Delays And Quality Of Service Constraints
(Indian Institute of Science, 2005-11-10)
In this thesis, we consider optimal control problems arising in high-speed integrated communication networks with Quality of Service (QOS) constraints. Integrated networks are expected to carry a large variety of traffic ...
Electrical Properties Of Diamond Like Carbon Films In Metal-Carbon-Silicon (MCS) Structure
(Indian Institute of Science, 2006-01-18)
Amorphous carbon film with Diamond like properties is the subject of intense interest in the past one and half decade. The unusual properties of these diamond like carbon films arise from the preponderance of SP3 tetrahedral ...
Interference Cancelling Detectors In OFDMA/MIMO/Cooperative Communications
(2009-09-02)
In this thesis, we focus on interference cancelling (IC) detectors for advanced communication systems. The contents of this thesis is divided into the following four parts:
1. Multiuser interference (MUI) cancellation in ...
A Study On Effects Of Phase - Amplitude Errors In Planar Near Field Measurement Facility
(Indian Institute of Science, 2006-07-26)
Antenna is an indispensable part of a radar or free space communication system. Antenna requires different stringent specifications for different applications. Designed and fabricated for an intended application, antenna ...
Three-Layer Electromagnetically Coupled Circular Microstrip Antennas
(Indian Institute of Science, 2006-10-13)
Presented in this thesis are the following experimental and theoretical investigations carried out on the three-layer electromagnetically coupled (EMC) circular microstrip antennas and their arrays.
1.Three-Layer EMC ...
High-Rate And Information-Lossless Space-Time Block Codes From Crossed-Product Algebras
(2007-10-23)
It is well known that communication systems employing multiple transmit and multiple receive antennas provide high data rates along with increased reliability. It has been shown that coding across both spatial and temporal ...
Subband Adaptive Filtering Algorithms And Applications
(Indian Institute of Science, 2007-03-26)
In system identification scenario, the linear approximation of the system modelled by its impulse response, is estimated in real time by gradient type Least Mean Square (LMS) or Recursive Least Squares (RLS) algorithms. ...
Design And Performance Analysis Of A New Family Of Wavelength/Time Codes For Fiber-Optic CDMA Networks
(2007-11-16)
Asynchronous multiplexing schemes are efficient than synchronous schemes, in a
bursty traffic environment of multiple access local area network (LAN), as fixed
bandwidth is not allocated among the users and there is no ...
Phase Sensitive Estimation Of Fluorescence Lifetime For Fiber Optic Biosensors
(Indian Institute of Science, 2005-10-04)
Fluorescence lifetime determination and allied studies find application in spectroscopy in general and fiber optic biosensors in particular. Instruments and sensors cited in literature however use open loop, intensity based ...
Scheduling For Stable And Reliable Communication Over Multiaccess Channels And Degraded Broadcast Channels
(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 ...
