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 ...
Low Power LO Generation Based On Frequency Multiplication Technique
(2008-08-27)
TO achieve high level of integration in order to reduce cost, heterodyne architecture has made way for low-IF and zero-IF (direct conversion) receiver architectures. However, a very serious issue in implementing both zero ...
Electronic Access Control Systems: A New Approach
(Indian Institute of Science, 2006-08-30)
Security systems are gaining increasing importance in recent times to protect life and valuable resources. Many advanced methods of providing security have been developed and are in use in the last few decades. Of these, ...
Estimation Of Object Shape From Scattered Field
(Indian Institute of Science, 2005-09-27)
The scattered field from an object, when illuminated with ultrasound, is useful in
the reconstruction of it's cross section - a problem broadly classified as 'tomography'. In
many situations of medical imaging, we will ...
Studies on Amorphous Silicon Thin Films Doped with Aluminium
(Indian Institute of Science, 2005-10-25)
Amorphous Silicon(a-Si) films have attracted the attention of several investigators as it is an economical material for devices. One of the problems that is addressed is the doping of these films after they are prepared.
In ...
Design Of Linear Precoded MIMO Communication Systems
(2009-07-09)
This work deals with the design of MT transmit, MR receive antenna MIMO (Multiple Input Multiple Output) communication system where the transmitter performs a linear operation on data. This linear precoding model includes ...
Coding For Multi-Antenna Wireless Systems And Wireless Relay Networks
(2009-03-04)
Communication over a wireless channel is a challenging task because of the inherent fading effects. Any wireless communication system employs some form of diversity improving techniques in order to improve the reliability ...
Improved GMM-Based Classification Of Music Instrument Sounds
(2009-03-19)
This thesis concerns with the recognition of music instruments from isolated notes. Music instrument recognition is a relatively nascent problem fast gaining importance not only because of the academic value the problem ...
