1. 1. Machine Learning Enabled Nonlinear Phase Noise Mitigation for Coherent Optical Systems

   Master-uppsats, Lunds universitet/Atomfysik; Lunds universitet/Fysiska institutionen

   Författare :Sergio Steven Gutierrez; [2020]
   Nyckelord :QAM; NLIN; NLPN; Machine Learning; Coherent Optical Communication; Nonlinear Noise Compensation; Physics and Astronomy; Technology and Engineering;

   Sammanfattning : In the current development of coherent optical communication systems, nonlinear noise is considered to be the ultimate bottleneck when extending the transmission length. In this report we suggest a nonparamter digital signal processing scheme to extend the transmission length of a fiber link. LÄS MER

3. 2. Methods for Automatic Hydraulics Calibration in Construction Equipment

   Master-uppsats, Mälardalens högskola/Inbyggda system

   Författare :Peter Charbachi; Filippo Ferrario; [2018]
   Nyckelord :;

   Sammanfattning : In this thesis we investigate the problem of automatic calibration and control of hydraulic components in the domain of construction equipment. Methods that are able to remove a costly manual approach in favour of an automatic one are investigated and evaluated. LÄS MER
