Following are the 4th year projects that I am offering for the 2001 fall semester. The projects are listed not necessarily in the order of preference. I am open to suggestions by the students as well. Those interested are wellcome to visit my office and discuss the projects. Please drop by my office (EA106) or  get an appointment by phone (2902339) or by e-mail (ider@ee.bilkent.edu.tr).

1) ELECTRICAL IMPEDANCE TOMOGRAPHY (EIT)
PURPOSE: Obtaining the internal conductivity distribution of a conductive object using measurements made on the boundary.
METHODS: Finite Element Method (FEM) will be used to solve for potential and electrical fields inside the object. Matrix inversion will be used to obtain inside conductivity distribution. Development environment will be MATLAB.

2) ELECTROCARDIOGRAM (ECG) SIGNAL PROCESSING
PURPOSE: To extract diagnostic information from ECGs recorded from patients.
METHODS: Spectral estimation using FFT and autoregressive modeling and other signal processing techniques will be implemented using preferably MATLAB and a user interface will be developed.

3) WEB BASED ANALYSIS OF TIME SERIES
PURPOSE: A web site will be developed so that a remote user who has recorded time series (signals in time) in the remote site  will analyze them using signal processing tools on the server.
METHODS: Java applets and a user interface will be developed.

4) WEB BASED SIMULATION OF DYNAMIC SYSTEMS
PURPOSE: A web site will be developed so that a remote user can enter the parameters (coefficients) of a dynamic system (system modelled by simultaneous differential equations) and specify its inputs so that the output waveforms are calculated on the server and displayed on the client PC. A specific dynamic system will be implemented.
METHODS: Tools of Microsoft Visual Studio will be used and a user interface will be developed.

5) DEVELOPMENT OF A USB DRIVER FOR SIGNAL ACQUISITION
PURPOSE: A device driver for the Universal Serial Bus (USB) of the PC will be developed for acquiring analog signals in real time with up to 10000 samples/second sampling rate.
METHODS: C++ will be used to write the Virtual Device Driver (VxD) and a user interface will be developed for visualization of the signals in real time on the computer screen.

6) DDS function generator 2003-2004

It this project a Direct Digital Synthesizer (DDS) circuit will be designed and implemented on a 1 million gate Zilinx FPGA chip. The circuit will be based on DDS technique which is based on calculating and adding the necessary phase advance to carrier phase by accumulating the phase information at a digital register. Upon the successful generation of the basic frequencies, additional features like amplitude and phase/frequency modulation and different type of waveforms will be added along with a programming interface.

Typical steps of the project are:
1.    Literature survey,
2.    Design of the circuit,
3.    Implementation,
4.    Test,
5.    Corrections,
6.    Final report and presentation

The project will be cosupervised by Tarık Reyhan and Yusuf Ziya İder from the Department of Electrical and Electronics Engineering.
 

7) DPSK modulator and demodulator 2003-2004

It this project a circuit which is composed of a seperate DPSK modulator and a seperate DPSK demodulator will be designed and implemented on a 1 million gate Zilinx FPGA chip. The circuit will output a DPSK modulated IF signal by creating the necessary I ( In phase) and Q (Quadrature) signals and adding them, and demodulate the IF signal by resolving the data from the I and Q signals. Upon the completion of the circuit, certain mesurements like BER curve, sensitivity against frequency shifts, which are important for characterization of communication systems will be carried out.
Typical steps of the project are:
1.    Literature survey,
2.    Design of the circuit,
3.    Implementation,
4.    Test,
5.    Corrections,
6.    Final report and presentation

The project will be cosupervised by Tarık Reyhan and Yusuf Ziya İder from the Department of Electrical and Electronics Engineering.
