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 ...
IMAGINE : An Intelligent Electonic Marketplace
(Indian Institute of Science, 2007-01-16)
In recent times, the Internet revolution has spawned numerous innovative enterprises-virtual companies, and electronic markets. Electronic markets (or digital markets) are scalable web-based platforms for buyers, sellers, ...
Algorithms For Efficient Implementation Of Secure Group Communication Systems
(2007-10-23)
A distributed application may be considered as a set of nodes which are spread across the network, and need to communicate with each other. The design and implementation of these distributed applications is greatly simplified ...
Efficient Bandwidth Constrained Routing Protocols For Communication Networks
(2007-10-24)
QoS routing is one of the major building blocks for supporting QoS in communication networks and, hence, a necessary component of future communication networks. Bandwidth- Constrained Routing Algorithm (BCRA) may help to ...
Study On Overmodulation Methods For PWM Inverter Fed AC Drives
(Indian Institute of Science, 2007-05-10)
A voltage source inverter is commonly used to supply a variable frequency variable voltage to a three phase induction motor in a variable speed application. A suitable pulse width modulation (PWM) technique is employed to ...
Resonant Transition Topologies For Push-Pull And Half-Bridge DC-DC Converters
(2007-10-23)
Switched mode power supplies (SMPS) are being extensively used in most power conversion processes. The analysis, design and modeling processes of hard-switched converters are mature, where the switching frequency was limited ...
