1. 6. Overcoming Inter-carrier-interference in OFDM System

   University essay from Linköpings universitet/Kommunikationssystem

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

   Abstract : 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. READ MORE

3. 7. Efficient Transmission over Unknown Channels

   University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

   Author : Ranjitha Gubbi Suresh; [2020]
   Keywords : Multi-Layer Transmission; RBIR; HARQ; mixing layers; successive demodulation; Wi-Fi; Technology and Engineering;

   Abstract : In recent years, digital transmission techniques have been continuously evolving by employing increasingly more advanced Modulation and Coding Scheme (MCS). However, when the wireless channel is varying rapidly, it is hard or even impossible for the transmitter to select the proper MCS. READ MORE

4. 8. Bearing Diagnosis Using Fault Signal Enhancing Teqniques and Data-driven Classification

   University essay from Linköpings universitet/Fordonssystem

   Author : Benjamin Lembke; [2019]
   Keywords : Bearing diagnosis; rolling element bearings; predictive maintenance; signal processing; fault detection; gearbox diagnosis; support vector machine; svm; binary classification; one class classification; machine learning; feldetektion; diagnos; feldiagnos; växellåda; signalbehandling; maskininlärning;

   Abstract : Rolling element bearings are a vital part in many rotating machinery, including vehicles. A defective bearing can be a symptom of other problems in the machinery and is due to a high failure rate. Early detection of bearing defects can therefore help to prevent malfunction which ultimately could lead to a total collapse. READ MORE

5. 9. Design and Implementation of a 5.8 GHz superheterodyne FM Video Receiver

   University essay from Linköpings universitet/Fysik och elektroteknik; Linköpings universitet/Tekniska fakulteten

   Author : Carl-Johan Stålberg; [2019]
   Keywords : Superheterodyne Receiver; 5.8 GHz; FM;

   Abstract : This master thesis presents the design and implementation of a super heterodyne 5.8 GHz receiver system for wireless transmission of phase alternating line (PAL) composite video signals. The system is implemented using surface and hole mounted devices on four separate printed circuit board (PCB) stages. These stages include a 5. READ MORE

6. 10. Vicinity Integrated Circuit Card Emulation of ISO15693 in NFC Devices

   University essay from Uppsala universitet/Institutionen för informationsteknologi

   Author : Elmar Xander van Rijnswou; [2018]
   Keywords : ;

   Abstract : This thesis describes the work flow of integrating a new digital design in an existing integrated circuit, the SN100V designed by NXP. The new digital design enables theSN100V for emulating ISO 15693 card, which is not available yet in any near field radio device. READ MORE
