1. 1. 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.

   Abstract : The rapid changes and developments in cellular and wireless networks aim to provide more reliable communications with high data rate transmission. So far, one solution which is being considered for improving the reliability and eciency of mobile communications is cooperative communications. READ MORE

4. 3. Measurement Based Vehicle-to-Vehicle Multi-link Channel Modeling and Relaying Performance

   University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

   Author : Xi Chen; [2015]
   Keywords : V2V; wireless; channel model; multilink; relaying; sum of sinusoids; correlated Gaussian; maximum likelihood estimation; Technology and Engineering;

   Abstract : There has been intense research in vehicular communication in order to provide reliable low-latency vehicular communication links for developing intelligent transportation system (ITS). As one of the important properties, vehicle-to-vehicle (V2V) communication is learned to be inherently non-stationary due to the high mobility of both transmitter (TX) and receiver (RX). READ MORE

5. 4. 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
