  1. 16. Performance Analysis of a MIMO Cognitive Cooperative Radio Network with Multiple AF Relays

    University essay from Blekinge Tekniska Högskola/Institutionen för tillämpad signalbehandling

    Author : Advaita Advaita; Mani Meghala Gali; [2016]
    Keywords : Cognitive radio; Cooperative communications; Space time coding; MIMO systems; Outage probability;

    Abstract : With the rapid growth of wireless communications, the demand for the various multimedia services is increasing day by day leading to a deficit in the frequency spectrum resources. To overcome this problem, the concept of cognitive radio technology has been proposed which allows the unlicensed secondary user (SU) to access the licensed spectrum of the primary user (PU), thus improving the spectrum utilization.

  5. 19. Back-pressure-like mechanisms on relay selection policies for cooperative diversity systems

    University essay from KTH/Reglerteknik

    Author : Dimitrios Poulimeneas; [2015]
    Keywords : ;

    Abstract : The topic of the current thesis is the reduction of the average packet delay in two-hop wireless cooperative networks with buffer-aided relays. This type of networks is of particular interest since it constitutes the building block for extended networks with multiple hops and numerous relays. READ MORE

  6. 20. 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 ingenjörsvetenskap

    Author : Andawattage Chaminda Janaka Samarasekera; [2014]
    Keywords : Cognitive Radio; Weibull Fading Channels; Cooperative Communication; Cognitive Relay Networks;

    Abstract : 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.
