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 3-hop using DAF and DF over 2-hop Relaying Protocols

   University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

   Author : Faisal Mehmood; Muneeb Ejaz; [2013]
   Keywords : Bit Error Rate; Cognitive Radio; Decode Amplify and Forward; Energy Detection; Probability of Detection; Rayleigh Fading; Relay Network;

   Abstract : In wireless Communication, the need of radio spectrum increases nowadays. But in the system we are losing approximately 82-86% of spectrum most of the time due to the absence of Primary User (PU). To overcome this issue Cognitive Radio (CR) is an admirable approach. READ MORE

5. 4. A Study of the Next WLAN Standard IEEE 802.11ac Physical Layer

   University essay from KTH/Signalbehandling
