1. Techniques for Efficient Implementation of FIR and Particle Filtering
Abstract : FIR filters occupy a central place many signal processing applications which either alter the shape, frequency or the sampling frequency of the signal. FIR filters are used because of their stability and possibility to have linear-phase but require a high filter order to achieve the same magnitude specifications as compared to IIR filters. READ MORE

2. Optimization of Rotations in FFTs
Abstract : The aims of this thesis are to reduce the complexity and increasethe accuracy of rotations carried out inthe fast Fourier transform (FFT) at algorithmic and arithmetic level.In FFT algorithms, rotations appear after every hardware stage, which are alsoreferred to as twiddle factor multiplications.

3. Design and Fabrication of III-V Semiconductor Devices for Millimetre- and Submillimetre Wave Applications
Abstract : Devices (various types of diodes) have been fabricated in several different III-V semiconductors (AlxGa1-xAs, In1-xGaxAs, and InAs). The III- V compound semiconductors lend themselves well to high frequency applications due to the high electron mobility that can be obtained. READ MORE

4. Contributions to low-complexity digital filters
Abstract : In this thesis we discuss design and implementation of low-complexity digital filters. Digital filters are key components in many digital signal processing (DSP) systems. Typical applications include interpolation, decimation, and noise suppression.The work presented in the thesis can be divided into four parts. READ MORE
