  • Developing a Distributed MIMO Channel Model Framework for Investigating the Reliability and Multi User Interference

  • ​In order to use wireless communications in harsh environments it is necessary to develop new technologies which improve the reliability of the data transmission. One method to reach this goal is the distributed MIMO approach, where multiple transmitter at different locations send the same information to a receiver at the same time and frequency. On one hand, this improves the overall reliability, but it also increases interference for other users, negatively affecting their reliability and capacity. In order to investigate the relationship between reliability improvement for one user and performance degradation for multiple users, it is necessary to develop a simulation framework. Therefore, in this work, a flexible channel modelling framework will be developed for the transmission of parallel data connection. The framework should be adaptable to different frequency bands and environmental conditions. Here, special focus is on channel models for unlicensed frequency bands (below 6 GHz) which are usually used for WLAN. After the successful implementation of the channel models and distributed MIMO topologies, the topic can be extended to study methods for interference cancellations.

    Goal of this work:

    Implementation of basic channel models (fast fading, slow fading) for one access point with multiple antennas

    Investigation of distributed MIMO topologies

    Extending channel models for different industrial environments (optional) 

    Investigating methods and architectures for interference cancellation (optional)

    Background information/projects:

    In order to replace current wired technologies (e.g. fieldbus systems) in industrial communications networks, new radio air interfaces have to be developed which are capable to guarantee the same transmission (Quality of Service) requirements as the already existing wired solutions. The main challenges here come along with very dynamic and time-dispersive behavior of the propagation channels. This is due to the extraordinary characteristics of industrial environments (e.g. excessive multipath scattering effects due to the abundance of many metallic scatterer, moving metallic objects like robots etc.). Therefore, the goal of the research project proWiLAN is to develop new techniques and methods for wireless local area network technologies to address varying demands of different human-to-machine applications (augmented reality,mobile panel control etc.) for industrial usage.

Current job offers for undergraduate students

  • Evaluation of FPGA C-API

  • ​Evaluation of FPGA C-API

    National Instruments LabView CSDS is a versatile programming tool for FPGA. To access the running FPGA, NI offers an application programming interface (API) for programmatically controlling the FPGA program from outside LabView. 
    In this work, the student assistant should evaluate the usability of this API for standalone applications. 


    Task:
    • Understanding the interface of the NI FPGA C-API
    • Translate an existing LabView Program into C or Python
  • Number of jobs: 1
  • Begin at: 10/2/2017
  • Time period: 3 month
  • Requirements:
    • Advanced knowledge in C and/or Python Programming
    • ​Fundamental knowledge in wireless communication systems

  • Contact: Dipl.-Ing. Maximilian Matthe
  • Evaluation FPGA High-Level Synthesis Tools

  • ​Evaluation FPGA High-Level Synthesis Tools

    National Instruments LabView CSDS is a versatile programming tool for FPGAs. In particular, it allows to integrate foreign HDL code into an FPGA. High-Level Synthesis allows to design FPGA programs in high-level languages, such as
    • Matlab, via Matlab HDL Coder
    • C, via Xilinx High-Level-Synthesis Tools
    • SystemC
    In this work, the student should thoroughly evaluate (one of) these options for compatibility with LabView.

    Task:
    • Follow the tutorials of the HLS tool
    • Integrate the HDL output of the HLS tool into LabView Code
    • ​Finish a small project using the HLS tool in combination with LabView.

  • Number of jobs: 3

  • Time period: 6 months
  • Requirements:

    • ​Understanding of FPGA architectures and programming
    • Advanced knowledge in C and/or Matlab

  • Contact: Dipl.-Ing. Maximilian Matthe
  • Design of a Framework to extract PHY (processing) latencies from an LTE implementation

  • A ground work has been developed to evaluate the physical layer (PHY) processing times of the National Instruments LTE Design Framework. However, this simulation takes 20 minutes on a computer, approximately. The next step is to run the same LTE implementations on the FPGA again and to extract the latencies of interest in an automated way with significantly reduced time consumption, i.e. in the order of several seconds. ​The tasks of this project are

    • Implementation of a standalone PHY on FPGA
    • Development of a framework to evaluate the performance of this implementation


  • Number of jobs: 1
  • Time period: 4 months, extension possible.
  • Requirements:
    • Basic knowledge and understanding of wireless communication systems;
    • Experience with Labview would be of help but isn’t mandatory;
    • Strong analytical and problem-solving skills;
    • Motivated and self-driven.
