1. Initial access in 5G mmWave networks with different base station parameters
Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)Sammanfattning : Nowadays in the fifth generation (5G) communication systems, millimeter wave (mmWave) has aroused interest to not only industrial use but also network operators due to the massive amount of bandwidth available at mmWave frequencies. Initial access in cellular systems is an essential procedure in which new mobile user equipment (UE) establishes a connection with a base station (BS). LÄS MER
2. Modeling, Simulation and Correlation of Drag losses in a Power Transfer Unit of an All- Wheel Drive System
Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)Sammanfattning : A Power Transfer Unit (PTU) of an All-Wheel Drive System is a hypoid gear transmission unit that distributes the power from the vehicle transmission to all wheels of the vehicle. This thesis aims at increasing the fidelity of the analytical power loss calculation methods through test data correlation and develop a 1D simulation model that can be used to evaluate the drag losses in the PTU at early design stages.

3. Dynamic Analysis of an Automotive Power Transfer unit : Towards prediction of TE and housing vibrations
Master-uppsats, KTH/Maskinkonstruktion (Avd.)Sammanfattning : This work describes the use of Multi-Body Simulation (MBS) to create a virtual prototype of a geared drive called Power transfer unit (PTU). PTU is a subsystem of the all-wheel drive driveline responsible for transfer of power between front and rear axles in an Automobile. LÄS MER
4. Low Density Parity Check Encoder and Decoder on SiLago Coarse Grain Reconfigurable Architecture
Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)Sammanfattning : Low density parity check (LDPC) code is an error correction code that has been widely adopted as an optional error correcting operation in most of today’s communication protocols. Current design of ASIC or FPGA based LDPC accelerators can reach Gbit/s data rate. LÄS MER
5. Analysis of 5G Mobile Broadband Solutions in Rural and Remote Areas : A Case Study of Banten, Indonesia
Master-uppsats, KTH/Skolan för informations- och kommunikationsteknik (ICT)Sammanfattning : Providing a broadband access anytime and anywhere is one of the visions of the future 5G network. However, deploying a reliable network connection in remote/rural areas has been a challenging task because of its wide area that needed to be covered and a low density of user compared to urban area.
