1. 1. Performance Analysis of STTC-Based MIMO Under Cognitive RadioScenarios

   University essay from Blekinge Tekniska Högskola/Institutionen för datavetenskap

   Author : Sanjana Kankantee; Sai Praneeth Reddy Ganta; [2023]
   Keywords : Space-time trellis coding; MIMO; Cognitive radio; Performance; Bit error rate; Diversity; AWGN; Rayleigh fading; Detection; Spectrum.;

   Abstract : This thesis presents a comprehensive investigation into improving wireless transmission rates and reliability through the implementation of Space Time Trellis Codes(STTC). The study focuses on enhancing the coding gain, diversity gain, and flexible transmission capabilities, which are crucial for Error-Correcting Codes (ECC)in wireless communications. READ MORE

3. 2. Holistic View on Alternative Programming languages for Radio Access Network Applications in Cloud and Embedded Deployments

   University essay from Linköpings universitet/Programvara och system

   Author : Rasmus Karlbäck; Anton Orö; [2021]
   Keywords : c ; rust; go; programming language comparison; embedded systems; cloud deployments;

   Abstract : With the emergence of cloud based solutions, companies such as Ericsson AB have started investigating different means of modernizing current implementations of software systems. With many new programming languages emerging such as Rust and Go, investigating the suitability of these languages compared to C++ can be seen as a part of this modernization process. READ MORE

4. 3. Outage Probability Analysis of CooperativeCognitive Radio Networks Over κ − μ Shadowed Fading Channels

   University essay from Blekinge Tekniska Högskola/Institutionen för tillämpad signalbehandling

   Author : Mahathi Poreddy; [2016]
   Keywords : Cognitive Radio Networks; Cooperative Communications; Decode-and-Forward Relays; Multiple-relay; Outage Probability;

   Abstract : Over time, wireless technology advancements in the field of communications have been attracting every individual to turn into a wireless user. To accommodate the increasing number of users and to avoid the problem of spectrum scarcity, the concept of Cognitive Radio Network (CRN) has been developed. READ MORE

5. 4. 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.

6. 5. Optimal Power Allocation and Ergodic Capacity in Cognitive Radio Network

   University essay from KTH/Skolan för elektro- och systemteknik (EES)

   Author : Guanren Wen; [2016]
   Keywords : ;

   Abstract : Cognitive radio network allows the secondary users (SUs) in a secondary communication network (SCN) coexist with priority users in a priority communication network (PCN). The interference caused by SCN to PCN is required to be rational and not affected the quality of server within the PCN to each priority users (PUs). READ MORE
