    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. 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

  4. 13. Fuzzy Based power control system Using ANFIS and MIMO-OFDM Techniques in Cognitive Radio Networks

    University essay from Blekinge Tekniska Högskola/Institutionen för tillämpad signalbehandling

    Author : Mahesh Aleti; Rahamatulla Syed; Rajendra Prasad Chennupati; [2014]
    Keywords : Cognitive Radio; Power Control; the Fuzzy Interference System FIS ; ANFIS; “MIMO” “Multiple Input Multiple Output” ; “OFDM” “Orthogonal Frequency Division Multiplexing” ; AWGN; BER; SNR; Eb N0;

    Abstract : Cognitive Radio technology is used for efficient utilization of the spectrum. There are two types of users, one is the Primary user (PU), and the second one is the Secondary user (SU). In those users, PU is having the license to use the spectrum. The SU does not have the license to use the spectrum. READ MORE

  5. 14. 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
