                        PROJECTS UNDERTAKEN
                        ^^^^^^^^^^^^^^^^^^^

 1) Junior Year Homepaper:
   ^^^^^^^^^^^^^^^^^^^^^
   Topic : Spectral considerations in Modulation and Demodulation.
   Guide : Dr. V.M. Ranathunge.

   Abstract:
   ^^^^^^^^
        In this paper , various state of the art modulation techniques  like GMSK (Gaussian-filtered Mean Shift Keying), FQPSK (Filtered - QPSK),  and DJ-FQPSK (Double Jump Filtered - QPSK) were analysed and compared to  the conventional techniques like BPSK, QPSK and MSK. The focus during  this study was on the spectral properties of the modulation techniques  like the spectral efficiency, bandwidth ACI etc.
 
        This paper was inspired by the problems faced by the Giant  Meterwave Radio Telescope (GMRT) project, which is the world's largest  radio telescope. The problem was the spurious interference in the Radio  Astronomy bands due to the spectrally inefficient techniques being  employed by the Low Earth Orbiting satellites. This prompted a  comparative analysis of the available state of the art modulation  techniques and formed the inspiration for my junior home paper.

        This work was continued with a special focus on GMSK. The  modulation technique was simulated using the software PTOLEMY and its  performance was evaluated. The resultant paper won the second prize in  the IEEE student paper contest.
 

 2) Senior Home Paper:
   ^^^^^^^^^^^^^^^^^
   Topic : Array Signal Processing.
   Guide : Dr. Harish Parthirage.

        I am currently working on this paper.

   Abstract:
   ^^^^^^^^
        This project aims to look at the issues involved in the  processing of signals obtained from an array of radar sources. Issues  like noise cancellation and parameter estimation would be addressed in  the paper. The emphasis would be on a rigorous theoretical analysis and  this would finally be supported by the required computer simulations.
 

                           OTHER PROJECTS
                           ^^^^^^^^^^^^^^
  1)   Hardware implementation of Differential Pulse coded modulation and
       demodulation system .

  2)   Hardware project on the efficient generation of Pseudo-Random numbers.
 
  3)   Computerization (using IEEE 488 conventions) of an experiment used
       to measure the voltage vs light characteristic of an optical diode
       using the software LabWindows at the Society for Applied Microwave
       Electronics and Engineering Research (SAMEER).

Fields of interest:

 
Research Experience:
 
 1) A seminar on "Chaotic Dynamical Systems" -
   under Prof. Nilaweera (Ph.D Cal-Tech, Pasadena, CA)
   The objective was to survey the current developments
   in this upcoming field, in relation to communication
   systems. Motivated by the topic, and with continued
   support of the faculty, I am now extending my
   work in the direction of developing algorithms for
   estimation of noise corrupted chaotic signals.And
   this has thrown up some interesting original results
   on the nature of chaotic phenomena also.
 
ABSTRACT:
  Chaotic dynamical systems which have fractal attractors
give rise to time series whose fractal nature can be
exploited to estimate and also denoise an observed noisy
chaotic time series. The current work focusses on the
wavelet transform based methods for efficient estimation
algorithms.
 
 2) A B.Sc Project in scene analysis and image
    understanding -
          under Prof. U.B.Desai (Ph.D Johns Hopkins)
    In this the aim is to integrate the understanding
   of Hidden Markov Models with the standard segmentation
   and image interpretation approaches for a more holistic
   computer vision algorithm.
 

HIGHLIGHT : The original results in the project
above has been submitted for review to the CVPR
conference  US Virgin Islands organised by
IEEE Computer Society.
 

ABSTRACT : This paper describes a multiresolution based approach, which is
used to learn models of shapes and objects. Hidden Markov Models is used
as a probabilistic model for the shape. The primary shape features used
here is a polar coordinate representation of the object contour.
Multiresolution analysis of this feature set, is used to obtain feature
vectors which reflect the shape characteristics at various resolutions.
These derived feature vectors are used to train HMMs which then constitute
an abstraction of the shape. This approach has given very encouraging
results. The shape models so obtained are obtainable using a smaller
training set, are robust with respect to data perturbation and also
incorporate the ability to represent objects which have many degrees of
freedom like human hand etc
 
 3)  Prof. H. Pathirage and myself are working in
    the understanding of nonlinear systems, and also
    studying their identification using Higher Order
    Statistical Methods like cumulants and polyspectra.
    and possibly their VLSI realization.The idea is to
    cut down on computational complexity by using
    wavelet based approximations.
 
Projects Undertaken:
 
    a) Wavelets: Development of a wavelet transform
    based efficient synthesizer for various types
    of signals ( like for e.g. with dominant glitches etc)
 
    b) Implementation of Wavelet based fault analysis
    and data compression algorithm on the TMS320C25
    DSP fixed point processor for real time processing
 
    c) Realization of a Finite State Automaton using
    TTL logic (Lab Project).
 
    d) Implementation of a Digital Transmitter & Reciever
    with an Infrared link , the goal was to develop the
    circuitry using the fundamentals learned in the
    Communication Systems course .

To
  Prof.
  Department of Electrical Engineering,
  University of .

         I am a student of the Four Year B.Sc Program in University of Moratuwa, Colombo, currently in my final year of the Undergraduate program in Electrical Engineering.
         I will be applying to the Department of Electrical engineering at your university for admission to the Masters program leading to a doctoral degree commencing Fall 1997. It is in this regard that I want to seek certain clarifications and advice from you.I give below a brief description of my academic background and my resume for your perusal. I would be greatly obliged if you could spare me some time and go through the rest of the letter.

       My field of interests are Computer Vision, Signal/Image Processing.  At present I am working on my Undergraduate Thesis titled: "Deterministic Annealing and its application to computer vision", under the guidance of Prof. U.B. Silva(John Hopkins). In this project I have explored the deterministic annealing  ptimization algorithm, which was proposed by Prof K.Rose in his paper in information theory. After generalizing the proposed hierarchical clustering algorithm, it has to applied in the clustering of face images. It will also be modified so as to apply it in the training of HMM(hidden Markov Model) in place of k-mean algorithm. Thus we can study the effect of varying the no. of states on the HMM. HMM thus trained can be used to recognize objects.
         Further details of other voluntary projects I was involved in are enlisted in my resume.
     As you can see my field of interest greatly overlaps with that of yours, I am highly motivated to work under your able idance and also contribute to your group's research activities. I will be greatly obliged if you consider me for working under you.  But  due to unavoidable financial constraints, I shall have to fully depend upon financial assistance from the department or from the
University. Please let me know my chances of receiving it.
 
       To sum up, I would be glad if you could :
1. Provide me a frank evaluation of my chances of securing admission into a M.S. program leading to Doctoral degree Commencing Fall 1997.
2. Chances of securing financial assistanceship ( if possible under you )   for my study .

        I will be extremely happy if you reply to my queries and will be only too glad to provide any additional information you might require.

In this project we are exploring the possibility of representing general
non-stationary processes by a wavelet based expansion with random
coefficients. The decomposition of incrementally stationary,self similar
processes using a wavelet based expansion has been studied.Having established
that L2-[0,T] (which has a wavelet basis) is congruent to an RKHS-[0,T](RKHS-
reproducing kernel hilbert space of an autocorrelation function), we are
now considering how this structure could be exploited to obtain a wavelet
based expansion of the corresponding process.
