1. 11. Video Quality of Experience through Emulated Mobile Channels

   University essay from Blekinge Tekniska Högskola/Institutionen för kommunikationssystem

   Author : NARAYANA KAILASH AMUJALA; JOHN KENNEDY SANKI; [2014]
   Keywords : H.264 SVC; AWGN noise; Downlink power; QoE problems; User Interface.;

   Abstract : Over the past few years, Internet traffic took a ramp increase. Of which, most of the traffic is video traffic. With the latest Cisco forecast it is estimated that, by 2017 online video will be highly adopted service with large customer base. As the networks are being increasingly ubiquitous, applications are turning equally intelligent. READ MORE

3. 12. 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

4. 13. Performance evaluation of interleaving techniques for IEEE 802.15.4 transmissions

   University essay from Mittuniversitetet/Avdelningen för informations- och kommunikationssystem

   Author : Jiahuan Lei; Qingbi Liao; [2014]
   Keywords : interleaving; Matlab; Reed-Solomon; TinyOS; WSN; FEC; MicaZ;

   Abstract : In the wireless sensor network, the WLAN interference, multi-path fading andattenuation are the main reason for packets’ corruption. Forward errorcorrection is one of the methods for error mitigation. Many coding methods aredesigned to improve the reliability of wireless channel. READ MORE

5. 14. Low complexity algorithms for faster-than-Nyquistsign : Using coding to avoid an NP-hard problem

   University essay from KTH/Optimeringslära och systemteori

   Author : Emil Ringh; [2013]
   Keywords : ;

   Abstract : This thesis is an investigation of what happens when communication links are pushed towards their limits and the data-bearing-pulses are packed tighter in time than previously done. This is called faster-than-Nyquist (FTN) signaling and it will violate the Nyquist inter-symbol interference criterion, implying that the data-pulsesare no longer orthogonal and thus that the samples at the receiver will be dependent on more than one of the transmitted symbols.

6. 15. Performance evaluation of higher order modulations in OFDM systems

   University essay from Institutionen för fysik och elektroteknik (IFE)

   Author : Veerapu Sravankumar; Malineni Jayaram Navaneeth; Chandran Vivek; [2013]
   Keywords : ;

   Abstract : In this thesis we design and simulate OFDM (Orthogonal Frequency Division Multiplexing) to study the performance of the OFDM system at higher order modulation schemes. It is very important to evaluate performance of the communication system, to test the efficiency and quality of the service it can provide. READ MORE
