1. 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.

2. Channel Coding and Multiuser Detection for CDMA and Wireless Communications
Abstract : Next generation wireless communication systems will require support for many different applications as well as improved quality compared to existing second generation systems like GSM (Global System for Mobile communications). Since there will be more users and higher data rates, the capacity must also be increased. READ MORE

3. 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
