  1. 6. A comparison of 5G candidate waveforms subject to phase noise impairment at mm-wave frequencies

    University essay from KTH/Skolan för elektro- och systemteknik (EES)

    Author : Vicent Molés Cases; [2016]
    Keywords : ;

    Abstract : Frequencies above 6 GHz are being considered by mobile communication industry for the deployment of future 5G networks. Large channel bandwidths above 6 GHz are likely to be used to serve diverse use cases and meet extreme user requirements. READ MORE

  3. 7. 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. 8. 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. 9. 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

  6. 10. 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
