  1. 11. 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

  3. 12. 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

  4. 13. Designing of LTE-Advanced Downlink Transceiver on a Physical Layer

    University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

    Author : Samiallah Shahid; Saqib Mohammad; [2013]
    Keywords : LTE-Advanced; Downlink; Transceiver; Physical Layer;

    Abstract : The evolved version of LTE is LTE-Advanced which is being developed by 3GPP. LTE-Advanced will meet or go beyond the requirements of the International Telecommunication Union (ITU) for the fourth generation (4G) radio communication standard known as IMT-Advanced. LTEAdvanced is primarily considered as a part of Release 10 of 3GPP specifications. READ MORE

  5. 14. Channel estimation in mobile wireless systems

    University essay from KTH/Signalbehandling

    Author : Pazi Alli Idd; [2012]
    Keywords : Time-variant channel; Discrete Prolate Spheroidal Sequences DPSS ;

    Abstract : The demands of multimedia services from mobile user equipment (UE) for achieving high data rate, high capacity and reliable communication in modern mobile wireless systems are continually ever-growing. As a consequence, several technologies, such as the Universal Mobile Telecommunications System (UMTS) and the 3rd Generation Partnership Project (3GPP), have been used to meet these challenges.
