16. The Performance of Dual-Hop Decode-and-Forward Underlay Cognitive Relay Networks with Interference Power Constraints over Weibull Fading Channels
University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskapAbstract : With the rapid development and the increasing use of wireless devices, spectrum scarcity has become a problem. The higher frequencies have bad propagation characteristics and the lower frequencies have low data rates, therefore the radio spectrum that is available for efficient wireless transmission is a limited resource.

17. Optimized Training Signal Design
University essay from KTH/SignalbehandlingAbstract : In this thesis, the problem of finding an optimal training sequence for estimating a MIMO flat fading channel with spatially and temporally correlated Gaussian noise is considered. The methods analyzed tailor the training sequence not only according to the known statistical CSI but also to the specific purpose the channel estimate will fulfill. READ MORE

19. Capacity Analysis of Cognitive Radio Relay Networks under Transmission and Interference Power Constraints
University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskapAbstract : This thesis investigates the performance of cognitive radio relay networks (CRRN) in Rayleigh fading channel under various power constraints. Here spectrum sharing approach is considered, whereby a secondary user (SU) may be allowed to transmit simultaneously with a primary user (PU) as long as SU interference to PU remains below a tolerable level.
