Efficient wireless communication systems with high data rates and the integration of localization and sensing technology into such systems raises the demand for realistic models of the propagation characteristics of radio frequency (RF) channels at different frequency bands. In order to create such channel models, high-performance channel sounding is required. Unfortunately, channel sounders that combine crucial parameters such as large bandwidth, fast beam switching and high dynamic range are still very costly and difficult to build.

The goal of this master project is to implement fast channel sounding on the software-defined radio (SDR) USRP X410. In-house mmWave frontends, consisting of phased array antennas and up/down converters, should be used to take measurements for the 28 GHz mmWave band. For that, the onboard RFSoC of the USRP X410 needs to be programmed to perform real-time channel impulse response (CIR) measurements. Measurement results should be evaluated and compared to existing measurements of a different channel sounder.
