1. 16. Analysis of the performance of Hybrid TWDM Passive OpticalNetworks (NG-PON2)

   Master-uppsats, Linnéuniversitetet/Institutionen för fysik och elektroteknik (IFE)

   Författare :Rameez Ahmed Khan; [2021]
   Nyckelord :Next Generation Passive Optical Networks NG-PONS ; Time Division Multiplexing TDM ; Wavelength Division Multiplexing WDM ; Hybrid Passive Optical Networks; Time and Wavelength Division Passive Optical Networks TWDM PON ;

   Sammanfattning : In this study, a review of research literature has been carried out to investigate Hybrid Time and wavelength Division Multiplexing techniques with respect to reach, split ratio, and speed of the network. This was done to overcome challenges presented by Passive Optical Networks, such as the reach and the high split ratio. LÄS MER

3. 17. A Specification for Time-Predictable Communication on TDM-based MPSoC Platforms

   Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Författare :Kelun Liu; [2021]
   Nyckelord :Communication; Time-Predictability; Network-on-Chip; Software Specification; Worst-Case Communication Time; Kommunikation; Tid Förutsägbarhet; Nätverk-på-Chip; MjukvaruSpecifikation; Kommunikationstid i Värsta Fall;

   Sammanfattning : Formal System Design (ForSyDe) aims to bring the design of multiprocessor systems-on-chip (MPSoCs) to a higher level of abstraction and bridge the abstraction gap by transformational design refinement. The current research is focused on a correct-by-construction design flow, which requires design space exploration including formal models of computation and timepredictable platforms. LÄS MER

4. 18. Overcoming Inter-carrier-interference in OFDM System

   Magister-uppsats, Linköpings universitet/Kommunikationssystem

   Författare :Fukang Guo; Luoan Lu; [2021]
   Nyckelord :ICI; OFDM; TDCP; FDCE; Windowing-OFDM; 5G;

   Sammanfattning : This master thesis aims for Inter-carrier interference (ICI) mitigation in orthogonal frequency division multiplexing (OFDM) system by considering designs of frequency domain cyclic extension(FDCE) and optimal windowing pulse shape. Although OFDM system has been put forward in the 1970s, it has just emerged in 4G. LÄS MER

5. 19. Dual-polarized feed for mmWave lens antennas

   Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Författare :Juan Luis Albadalejo Lijarcio; [2020]
   Nyckelord :;

   Sammanfattning : The fact of being bulky and not very cost-efficient made lens antennas not to be takenmuch into account in the past. Nowadays, this kind of antennas has attracted moreattention due to the increasing demand of higher frequencies in 5G, where lensesbecome considerably smaller. LÄS MER

7. 20. Energy Efficiency of 5G Radio Access Networks

   Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Författare :Saivenkata Krishna Gowtam Peesapati; [2020]
   Nyckelord :Resource adaptation; Activity factor; Power modeling; Energy-efficiency; 5G; Q-learning;

   Sammanfattning : The roll-out of the fifth-generation (5G) wireless networks alongside existing generations and characterized by a dense deployment of base stations (BSs) to serve an ever-increasing number of users and services leads to a drastic increase in the overall network energy consumption (EC). It can lead to an unprecedented rise in operational expenditure (OPEX) for the network operators and an increased global carbon footprint. LÄS MER
