1. Hardware Architectures for Wireless Communication - Symbol Detection and Channel Estimation
Sammanfattning : In this thesis different aspects of baseband implementation of mobile communication systems is treated. The content is focused on symbol detection and channel estimation in MIMO and OFDM. The thesis deals with the complete chain from algorithm to silicon implementation within these areas. LÄS MER
2. Serially Concatenated Space-Time Coded Continuous Phase Modulation
Sammanfattning : Certain problems associated with reliable digital wireless communication over a frequency-flat slow Rayleigh fadingchannel are treated, when the transmitted signal is modulated using continuous phase modulation (CPM) due to the desirable properties of CPM. The primary focus of attention is on detection strategies, and the thesis proposes iterative detection algorithms for CPM signals transmitted over frequency-flat slow Rayleigh fading channels.

3. Reduced Complexity Techniques for Iterative Decoding
Sammanfattning : .... LÄS MER
4. Multi-level modulation formats for high-speed optical transmission systems
Sammanfattning : Over the past several years, the use of multi-level modulation formats has enabledsignificant improvements in the field of optical fiber communication, particularlyin terms of per-channel bit-rate (i.e., line-rate) and spectral efficiency (SE), byencoding multiple bits per symbol.

5. Compensation of Laser Phase Noise Using DSP in Multichannel Fiber-Optic Communications
Sammanfattning : One of the main impairments that limit the throughput of fiber-optic communication systems is laser phase noise, where the phase of the laser output drifts with time. This impairment can be highly correlated across channels that share lasers in multichannel fiber-optic systems based on, e.g. LÄS MER
