  3. 2. Evaluation of Geopositioning Using Frequency Responses From Radio Propagation Measurements

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

    Author : Jessica Ye; Johan Lesko; [2023]
    Keywords : ;

    Abstract : Satellite reliant navigation systems may struggle in urban environments as tall buildings mayobstruct necessary direct lines of sight with satellites. There have been multiple studiesexamining how WIFI fingerprinting may be used for indoor positioning. READ MORE

  4. 3. Optimizing Load Balancing inRaytracing for Radio Frequency PropagationPredictive models developed for simulation systems

    University essay from Uppsala universitet/Institutionen för informationsteknologi

    Author : Wenhao Zhu; [2023]
    Keywords : ;

    Abstract : This thesis presents two predictive models with the aim of pre-allocating memory efficiently in the Ericsson Radio Frequency Propagation Simulation System through the prediction model, so as to achieve the effect of load balancing. The proposed approaches utilize interpolation and the Gradient Boosting Decision Tree (GBDT) method from machine learning for prediction and  apply both methods in multiple test scenarios. READ MORE
