  1. 6. 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

  3. 7. Design and implementation of LTE-A and 5G kernel algorithms on SIMD vector processor

    Abstract : With the wide spread of wireless technology, the time for 4G has arrived, and 5G will appear not so far in the future. However, no matter whether it is 4G or 5G, low latency is a mandatory requirement for baseband processing at base stations for modern cellular standards. READ MORE

  4. 8. Inductorless LNA and Harmonic-rejection Mixer for Wideband Direct-conversion Receiver

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

    Author : Anh Chu; [2015]
    Keywords : Ericsson; inductorless; harmonic-rejection; Noise-cancelling LNA; Mixer; LNA; Receiver; LTE-A; 4G Network; Technology and Engineering;

    Abstract : In this master thesis, combinations of noise-canceling LNA and harmonic-rejection mixers are investigated and compared to find an optimal inductorless receiver front-end for low-band (600-960MHz) FDD LTE-A network. The work was carried out in a modem development project at Ericsson Modems, Lund. READ MORE

  5. 9. Impact of Mutual Coupling among Antenna Arrays on the Performance of the Multipath Simulator System

    University essay from Avdelningen för elektronik, matematik och naturvetenskap

    Author : Dhayalini Ramamoorthy; [2014]
    Keywords : MIMO; MPS system; Antenna array;

    Abstract : This thesis work presents a study on the impact of mutual coupling among antenna arrays on the performance of the multipath simulator (MPS) system. In MIMO systems, it is a wellknown fact that the mutual coupling significantly affects their system performance. READ MORE
