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. 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.

4. 3. Performance Analysis of a Cooperative Communication Network Over κ - μ Shadowed Fading for Different Relaying Protocols

   University essay from Blekinge Tekniska Högskola/Institutionen för tillämpad signalbehandling

   Author : Alekhya Kodide; [2016]
   Keywords : Cooperative communications; κ−µ shadowed fading; relaying protocols; outage probability;

   Abstract : With the fast development of today’s multimedia services, engineers face a huge hurdle that is, the overwhelming need of highly reliable communication over long distances. Cooperative communication is a novel concept which tackles this problem effectively. READ MORE

5. 4. Exploiting the Direct Communication Link for Enhancing Effective Capacity Performance of Cognitive Radio Relay Networks

   University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

   Author : Md Abdul Matin Biswas; [2014]
   Keywords : Cognitive Radio; Quality of Service QoS ; Effective Capacity; Cooperative Relaying; Cognitive Relay Networks; Peak Interference Power Constraint; Delay QoS Constraint;

   Abstract : Nowadays, cognitive radio (CR) is a promising concept to improve the radio spectrum exploitation. CR has tremendous ability to enhance spectrum efficiency by allowing secondary users (SUs) to access licensed radio spectrum resource which is currently not being used by primary users (PUs).

6. 5. Fuzzy Based power control system Using ANFIS and MIMO-OFDM Techniques in Cognitive Radio Networks

   University essay from Blekinge Tekniska Högskola/Institutionen för tillämpad signalbehandling

   Author : Mahesh Aleti; Rahamatulla Syed; Rajendra Prasad Chennupati; [2014]
   Keywords : Cognitive Radio; Power Control; the Fuzzy Interference System FIS ; ANFIS; “MIMO” “Multiple Input Multiple Output” ; “OFDM” “Orthogonal Frequency Division Multiplexing” ; AWGN; BER; SNR; Eb N0;

   Abstract : Cognitive Radio technology is used for efficient utilization of the spectrum. There are two types of users, one is the Primary user (PU), and the second one is the Secondary user (SU). In those users, PU is having the license to use the spectrum. The SU does not have the license to use the spectrum. READ MORE
