Subject

Latency-sensitive applications like machine control, video telephony and virtual reality demand fast responses between two communicating devices. However, current WLAN standards are inherently not suitable for low-latency operation as they utilize half-duplex operation, which means that only one device can send at a time instant.
A concept that promises lower response times is full-duplex operation, which allows two devices to send simultaneously.

In the context of my scientific work, I deal with challenges arising from integration of full-duplex operation in upcoming WLAN standards, such as self-interference or synchronization.

My research interests are:

  • Full-duplex techniques for wireless systems
    • Simultaneous-transmit-receive frequency division duplex (FDD)
    • In-band full duplex (IBFD)
  • Self-interference cancellation in wireless systems
    • Nonlinear self-interference estimation
    • Neural network-based self-interference estimation
  • Machine learning for full-duplex systems
  • Latency-reducing techniques in WLAN systems
  • WLAN MAC layer simulations
