6. Selfish Dynamic Spectrum Access in Multichannel Wireless Networks : Complete and incomplete information analysis
Sammanfattning : The increasing popularity and widespread deployment of wireless data systems fuel the increasing demand for more spectrum. On the other hand, various studies measuring spectrum utilization show that there is a huge variation in spectrum utilization at different times and locations. LÄS MER
7. 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
8. Mobile Satellite Broadcast and Multichannel Communications : analysis and design
Sammanfattning : In this thesis, analytical analysis and design techniques for wireless communications with diversity are studied. The impact of impairments such as correlated fading is analyzed using statistical models. Countermeasures designed to overcome, or even exploit, such effects are proposed and examined. LÄS MER
9. Structured interface suppression in multichannel systems
Sammanfattning : .... LÄS MER
10. On Interference Rejection in Wireless Multichannel Systems
Sammanfattning : To meet the growing demands for service provisioning usingwireless access, efficient utilization of the available radiospectrum is a key issue of great importance. To achieve highspectrum efficiency, use of spectral efficient modulationmethods in combination with tight physical channel reuse areanticipated in future cellular communication systems. LÄS MER
