1. Optimizing Load Balancing inRaytracing for Radio Frequency PropagationPredictive models developed for simulation systems
University essay from Uppsala universitet/Institutionen för informationsteknologiAbstract : 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

2. Backscatter Communications for 6G
University essay from Lunds universitet/Institutionen för elektro- och informationsteknikAbstract : The success of future Internet of Things (IoT) depends on, among the other things, developing energy-effcient communication techniques that can enable information exchange among billions of IoT devices with ultra-low/zero power consumption requirements. Ambient backscatter communications is an emerging technology, which utilizes the ambient Radio Frequency (RF) signal as the carrier to reduce the form-factor, and the battery requirements of low-cost small sensor type communication devices.

5. Wireless wave propagation in city street canyons
University essay from Lunds universitet/Institutionen för elektro- och informationsteknikAbstract : This project aims to determine the characteristics of a wireless communication channel in city-street-canyon scenarios. The channel of a typical city intersection is modeled with a ray tracer and measured with a channel sounder. Then, the results of both tools are compared in terms of the local scattering function.
