  3. 2. 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. 3. Machine Learning for PAPR Distortion Reduction in OFDM Systems

    University essay from KTH/Signalbehandling

    Author : Manish Sonal; [2016]
    Keywords : Index Terms- OFDM; machine learning; PAPR; neural networks;

    Abstract : The purpose of the project is to investigate the possibility of using modern machine learning to model nonlinear analog devices like the Power Amplifier (PA), and study the feasibility of using such models in wireless systems design. Orthogonal frequency division multiplexing (OFDM) is one of the most prominent modulation technique used in several standards like 802. READ MORE

  5. 4. Optimization of Cognitive Radio in NLoS Backhauling of Small Cells

    University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

    Author : Paresh Kumar Lakhani; Ajay Gul; Fahad Naveed; [2013]
    Keywords : Backhauling; Cognitive Radio; Link Budget; Long Term Evolution LTE ; Non Line of Sight NLoS ; Small Cell.;

    Abstract : The increasing demand of data access and user experience result in deployment of new technologies (3G, LTE, WiMAX, Cognitive Radio), Long Term Evolution (LTE) is one of them which promises to fulfill the variable demand of subscribers through small cells instead of macro cells. The backhauling of the small cells in densely populated urban area is again a very difficult task to handle with Government regulations (eccentricities) and restrictions. READ MORE
