2. Channel Related Optimization of Wireless Communication Systems
Abstract : This thesis deals with different optimization problems in the design of wireless communication systems. It is mainly directed to the design of systems based on multicarrier techniques and orthogonal frequency division multiplex, OFDM, but some of the problems apply to single carrier systems as well.

3. Design and analysis of estimators for multicarrier modulation and ultrasonic imaging
Abstract : This thesis deals with two areas: multicarrier modulation and ultrasonic imaging. Although different in application, these fields have a lot in common. For instance, synchronization and channel estimation in communication systems correspond to time-delay estimation and system identification in ultrasonic imaging. READ MORE

4. Turbo Codes and Channel Estimation in Wireless Systems
Abstract : This thesis focuses on practical implementation issues of turbo codes with imperfectly estimated fading wireless channels and limited code length. Channel estimation can be divided into estimation of static parameters, such as constant timing and phase offset, and dynamic parameters, such as fading channel amplitudes. READ MORE
