   Nyckelord :WDM; SDM; SDN; routing and wavelength assignment; large-scale network; hardware resource; WDM; SDM; SDN; routing och tilldelning av våglängd; storskaligt nätverk; hårdvara resurs;

   Sammanfattning : Optical networking has been developing for decades and wavelength-division multiplexing (WDM) is the main technology used to carry signals in fiber-optical communication systems. However, its development has slowed because it is approaching the Shannon limit of nonlinear fiber transmission. LÄS MER

4. 28. RF system for mmWave massive MIMO

   Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknik

   Författare :Ziqi Zhou; Jingwei Wang; [2018]
   Nyckelord :Technology and Engineering;

   Sammanfattning : Due to rapid developments in communication technology, it is likely that 5G networks will be rolled out in 2019. To adapt to 5G, hardware will have to develop to meet the requirements of this new technology. The mmWave communication is one of the main elements of 5G technology. LÄS MER

5. 29. Upcycling av teckendisplaymodul : En adapter for styrkretsen Hitachi HD44780

   Uppsats för yrkesexamina på grundnivå, KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Författare :Dejan Ristic; [2018]
   Nyckelord :Upcycling; Embedded systems; multiplexing; Hitachi HD44780; character display; ATmega328; Upcycling ; Inbyggda system; multiplexering; Hitachi HD44780; tecken- display; ATmega328;

   Sammanfattning : Upcycling can be described as an activity where outdated or discarded products are used as raw-materials in the construction of a new object, for which an increased quality or value is achieved. Some ideas for upcycling of technologically simple products have prooved successful, in the sense that those ideas have become widespread and practically implemented within a certain target audience.

7. 30. Deep Learning for Error Prediction In MIMO-OFDM system With Maximum Likelihood Detector

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

   Författare :Baoqing She; [2018]
   Nyckelord :MIMO-OFDM; CRC; BLER; Detector; SINR; MCS Selection; Link Adaptation; Deep Learning; Neural Networks;

   Sammanfattning : To increase link throughput in multi-input multi-output (MIMO) orthogonal frequencydivision multiplexing (OFDM) systems, transmission parameters such as code rate andmodulation order are required to be set adaptively. Therefore, block error rate (BLER)becomes a crucial measure which illustrates the quality of the link, thus being used in LinkAdaptation (LA) to determine the transmission parameters. LÄS MER
