  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

    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

  3. 3. Exploiting the Overtones in Online Localization of Sound Sources

    University essay from Lunds universitet/Matematisk statistik

    Author : David Sundström; [2022]
    Keywords : Multi-pitch estimation; localization; block sparsity; sparse recursive least squares; online estimation; ADMM; adaptive dictionary; Mathematics and Statistics;

    Abstract : Localization of multiple sound sources from a microphone array is a challenging task that has been a research topic for decades. The challenges stem from the diversity of acoustic contexts due to reverberation and disturbances. READ MORE
