  1. 16. Evaluation of a Set of TCP Features over Narrowband Radio Bearer for Train Communication

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

    Author : Pajtim Buzolli; Jakub Tadeusz Mucha; [2016]
    Keywords : TCP; TCP Features; Circuit Switched; GSM-R; Packet Switched; GPRS; Train Communication; Technology and Engineering;

    Abstract : An engineering approach to the evaluation of the TCP as a narrowband bearer for short messages in the low latency train-trackside communication scenario is described in this report. The project was developed in cooperation with Bombardier Transportation Sweden AB as a part of the “ETCS over GPRS” venture. READ MORE

  3. 17. Software Defined Radio based MIMO channel sounding

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

    Author : Jens Elofsson; Peter Seimar; [2016]
    Keywords : channel sounding; MIMO; Zadoff Chu; M-sequences; USRP; FPGA; Technology and Engineering;

    Abstract : With todays increased use of smartphones and other wireless devices, the demands on the wireless networks have increased dramatically. This has prompted the re- search and development of new types of wireless systems using multiple antennas at both the transmitter and the receiver, known as MIMO. READ MORE

  4. 18. Lower bounds on the Q-factor for small oversampled superdirective arrays over a ground plane

    University essay from KTH/Skolan för elektro- och systemteknik (EES)

    Author : Masahiro Wakasa; [2016]
    Keywords : ;

    Abstract : Base station antennas for next generation mobile communication networks will be required to have a wide bandwidth for compatibility and support multi-beam applications. Antenna arrays are one possible candidate for a next generation base station antenna since they can obtain high directivity, support multi-beam and wide angle scanning. READ MORE

  5. 19. Pattern Reconfigurable MIMO Antennas for Multiband LTE Operation

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

    Author : Rui Ma; Ioannis Chountalas; [2015]
    Keywords : Technology and Engineering;

    Abstract : Nowadays, multiple antennas are becoming widely used in small mobile terminals as they can significantly improve wireless communication performance in terms of link reliability and spectral efficiency. Also, pattern reconfiguration is another new trend for antenna design as it enables the antennas to adapt to different propagation and user scenarios. READ MORE

  6. 20. Addressing non-conformities in a ERTMS implementation : Collecting non-conformities in ERTMS simulation and analyzing their management via a database

    University essay from KTH/Radio Systems Laboratory (RS Lab)

    Author : Laurier Ndikuriyo; [2015]
    Keywords : ERTMS; GSM; ETCS; Simulation; Non-conformity; Management; database; ERTMS; GSM; ETCS; simulering; icke-avvikelse; management; databas;

    Abstract : The European Rail Traffic Management System (ERTMS) aims to standardize train control command and communication systems in Europe. The main goal of its introduction is to develop trans-European railway traffic and increase competition. READ MORE
