1. Design of a wideband direct sequence spread spectrum radio transceiver ASIC
Sammanfattning : .... LÄS MER
2. ASIC implementable synchronization - and detection methods for direct sequence spread spectrum wideband radio receivers
Sammanfattning : .... LÄS MER
3. Subspace-Based Parameter Estimation Problems in Signal Processing
Sammanfattning : The effects of multipath-induced angular spread and non-zero band-width on narrow-band direction-of-arrival (DOA) estimation are investigated. In both cases expressions for the resulting estimation error are developed for the MUSIC, ESPRIT and WSF DOA estimators. LÄS MER
4. Interference Rejection in Wireless Communication Systems
Sammanfattning : This thesis is concerned with the problem of interference rejection in wireless communication systems. Different solutions are proposed, depending on the type of system under study and the amount of knowledge available about the signal and the propagation environment. LÄS MER
5. Multirate Codes and Multicarrier Modulation for Future Communication Systems
Sammanfattning : 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.
