11. Signal processing in massive MIMO systems realized with low complexity hardware
University essay from Lunds universitet/Institutionen för elektro- och informationsteknikAbstract : 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

12. Machine Learning for PAPR Distortion Reduction in OFDM Systems
University essay from KTH/SignalbehandlingAbstract : 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

13. Performance Evaluation of Error Correcting Techniques for OFDM Systems
University essay from Blekinge Tekniska Högskola/Institutionen för kommunikationssystemAbstract : 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

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)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
