BA/MA: ISAC for 6G base stations

Description

So far, the integration of communication and sensing into a single waveform has mainly been investigated through simulations and demonstrated using prototypes and demonstrators. Due to the improved Doppler resolution in the mmWave domain, the FR2 frequency range enables new opportunities for integrated sensing and communication.

b) ISAC transceiver with communication and sensing using a single base station. Source: [1]

For our research in this field, a commercially developed system is available, which operates in a licensed frequency band within a private campus network. The main focus is on exploiting the sensing capabilities of the base station to detect targets within the coverage area of the campus network. Based on this, algorithms are developed that may be applied in future generations of mobile communication systems.

Research Questions

  • Can current OFDM-based sensing approaches be transferred to future commercial systems?
  • What target detection performance and accuracy can be achieved in a private network where communication is the primary task?
  • Are there additional hardware-related effects that have not yet been considered in simulations?

Objectives of this Thesis

The objective of this thesis is to extend the sensing capabilities of a commercial ISAC system and to evaluate them using a simple measurement campaign.

  1. Familiarization with the fundamentals of OFDM and its suitability for ISAC applications.
  2. Initial investigations using the already implemented range estimation based on simplified correlation of TX and RX signals.
  3. Generation of IQ data through measurement campaigns and subsequent processing of the measurement data (primarily offline, in post-processing).
