  1. 1. Deep Neural Networks for dictionary-based 5G channel estimation with no ground truth in mixed SNR scenarios

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Matteo Ferrini; [2022]
    Keywords : 5G; Channel Estimation; Sparse Linear Inverse Problem; Approximate Message Passing; Neural Networks; 5G; kanaluppskattning; sparsamt linjärt inversproblem; approximativ meddelandeöverföring; neurala nätverk;

    Abstract : Channel estimation is a fundamental task for exploiting the advantages of massive Multiple-Input Multiple-Output (MIMO) systems in fifth generation (5G) wireless technology. Channel estimates require solving sparse linear inverse problems that is usually performed with the Least Squares method, which brings low complexity but high mean squared error values. READ MORE

  3. 2. Control System Simulator for MIMO Tank Level using Self-tuning PID-Fuzzy Adaptive Controller

    University essay from Högskolan i Gävle/Avdelningen för elektroteknik, matematik och naturvetenskap

    Author : Sinan Ibrahim; [2022]
    Keywords : ;

    Abstract : According to Oxford dictionary, the word intelligence is derived fromintellect, which is the ability of knowing, reasoning and understanding.Intelligent behaviour is thus the ability to reason, plan and learn, which in turnrequires access to knowledge. READ MORE

  4. 3. Adaptive Frequency Resolution for Downlink Beamforming in 5G NR

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

    Author : Johanna Bengtsson; [2021]
    Keywords : beamforming; MIMO; 5G; 5G NR; Technology and Engineering;

    Abstract : As the demand for higher data rates and lower latencies increase, together with the use of higher frequency bands, MIMO and beamforming have become an essential part of the 5G NR technology. Calculating the beamforming weights is a costly process, and reducing the frequency resolution of the weight calculations would save a significant amount of computational power. READ MORE

  5. 4. Acoustic Room Correction for Speaker Systems Using Signal Processing Techniques

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

    Author : Niklas Carlsson; Hanne Heingård; [2018]
    Keywords : Audio; Room correction; Noise; Network; MIMO; Technology and Engineering;

    Abstract : Loudspeakers are used in many different applications and play a vital role in various types of entertainment and communication. To optimize the listening experience, there is a need for an adjustment process to compensate for any effects the environment might have on the loudspeaker’s performance. READ MORE

  6. 5. Passive Inter-modulation Cancellation in FDD System

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

    Author : Fan Chen; [2017]
    Keywords : Technology and Engineering;

    Abstract : Passive inter-modulation (PIM) shows up when two or more RF signals are mixed together via the nonlinear passive devices. With the rapid development and expansion of the wireless com-munication networks, PIM is recognized as one of the most critical issues. READ MORE
