  1. 11. Modeling, Implementation and Evaluation of IEEE 802.11ac in Enterprise Networks

    University essay from Lunds universitet/Högskoleingenjörsutbildning i datateknik

    Author : David Åkerman; André Jönsson; [2016]
    Keywords : ns-3; wlan; 802.11ac; simulations; enterprise; Technology and Engineering;

    Abstract : Simulation studies are today an important tool in the development of new networks. For this purpose the NS-3 network simulator can be used. The focus of this thesis work lies on 802.11ac, the latest version of the Wi-Fi standard. READ MORE

  3. 12. A Study of Lattice Reduction Detection Techniques for LTE Systems

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

    Author : Liping Wang; [2016]
    Keywords : LTE; MIMO; Lattice Reduction; MMSE; ZF; ML; Kronecker Model; Rayleigh Fading Channel; Technology and Engineering;

    Abstract : MIMO (Multiple Transmit and Multiple Receive) antenna techniques are widely used in the most recent wireless communication standards. For example, LTE (Long-Term Evolution), WiMAX (Worldwide Interoperability for Microwave Ac- cess) and IEEE 802.11n have recently been rolled out across the world. READ MORE

  4. 13. Filter Bank Multi-Carrier Modulation

    University essay from KTH/Kommunikationsteori

    Author : Frédéric De Poret; [2015]
    Keywords : ;

    Abstract : During the last years, multi-carrier modulations have raised a particular interest due to their high spectral efficiency and the possible assumption of flat frequency fading. The most broadly used multi-carrier modulation is the CP-OFDM. READ MORE

  5. 14. Modulation Coding In A Radio Link And Data Transfer Application Using L2 VPN Ethernet Over MPLS In A Large Network

    University essay from Högskolan i Gävle/Avdelningen för elektronik, matematik och naturvetenskap

    Author : Dogan Varli; [2015]
    Keywords : Radio Link; Path Loss; GNS3; QAM; MPLS;

    Abstract : In this thesis work, the locations where we are unable to reach via fiber are considered for wireless transmission links. In the practical part of this thesis different modulation techniques and antenna sizes were analyzed  in order to provide the most efficient way of data transmission. READ MORE

  6. 15. Signal Classification Implemented by Wavelet Analysis and Support Vector Machine

    University essay from Avdelningen för elektronik, matematik och naturvetenskap

    Author : Qianyi Zhang; [2014]
    Keywords : ;

    Abstract : In this thesis, a method for signal classification has been developed and implemented on the platform of Matlab and Libsvm, which combines the techniques of wavelet analysis and support vector machine. The whole process is divided into three stages i.e. Signal Generation, Feature Extraction and Classification. READ MORE
