2. Multicarrier Modulation and Coding for Multichannel Systems
Abstract : In this thesis decision directed coherent detectors for single- and multicarriersystems employing an MMSE channel estimation technique is presented. Thedetectors are designed for Rayleigh fading channels and DQPSK or p/4-DQPSKmodulation and exploit knowledge of the fading process correlation. READ MORE

3. Multirate Codes and Multicarrier Modulation for Future Communication Systems
Abstract : In this thesis, new detection and modulation methods for multicarrier systems are presented. The proposed multicarrier detectors are based on feedback of previously detected symbols and the idea is to exploit the correlation, both in time between consecutive symbols, and in frequency between neighboring sub-carriers.

4. Nonlinearity in Broadband Wireless Communication Systems
Abstract : In the implementation of a digital communication system, there often exist imperfections that are not considered in the primary design. One such imperfection is the nonlinearity of the front-end devices. READ MORE

5. 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.
