  1. 11. Signal processing in massive MIMO systems realized with low complexity hardware

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

    Author : Sara Gunnarsson; Micaela Bortas; [2017]
    Keywords : massive MIMO; energy efficiency; 5G; low complexity; digital signal processing; supply voltage; Technology and Engineering;

    Abstract : The global mobile data traffic, as well as the energy consumption, for networks is constantly increasing. For this reason, techniques which can provide higher spectral efficiency while being more energy efficient are needed. READ MORE

  2. 12. 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. 13. Performance Evaluation of Error Correcting Techniques for OFDM Systems

    University essay from Blekinge Tekniska Högskola/Institutionen för kommunikationssystem

    Author : Yasir Javed Qazi; Jawad Ahmed Malik; Safwan Muhammad; [2014]
    Keywords : OFDM; Linear block codes; Convolution codes; Reed-Solomon codes;

    Abstract : Orthogonal frequency-division multiplexing (OFDM) systems provide efficient spectral usage by allowing overlapping in the frequency domain. Additionally, they are highly immune to multipath delay spread. READ MORE

  4. 14. Image Reconstruction using wavelet transform with extended fractional fourier Transform

    University essay from Blekinge Tekniska Högskola/Institutionen för tillämpad signalbehandling

    Author : Prahallada Reddy Tammireddy; Rajesh Tammu; [2014]
    Keywords : wavelet transform; Data encryption standards; Fractional fourier transform; Master of Science Programme in Electrical Engineering with emphasis on Signal Processing Masterprogram i Elektroteknik med inriktning mot signalbehandling;

    Abstract : Image reconstruction forms the basis of many applications in the fields of medicine, astronomy etc. Historically an image is reconstructed using several methods of which Fourier and wavelet transform methods formed the roots of present day technologies. READ MORE

  5. 15. Implementation of 64-point FFTs as a building block for OFDM-based standards with respect to different criteria

    University essay from KTH/Skolan för informations- och kommunikationsteknik (ICT)

    Author : Sarojanarayanamurthy Rajavari Krishnaih Lokanadhan; [2013]
    Keywords : ;

    Abstract : Abstract This master thesis implements a critical block: Fast Fourier Transform (FFT)/Inverse Fast Fourier Transform (IFFT) for standards using Orthogonal Frequency Division Multiplexing (OFDM). They are used in OFDM systems for modulating / demodulating subcarriers. READ MORE
