USRP-Based Platform for 26/28 GHz mmWave Experimentation

This paper presents an platform for 26/28GHz millimeter wave (mmWave) experimentation. We introduce an analog mmWave multi-beam antenna array, developed at TU-Dresden, that can be interfaced with regular software-defined radio (SDR) platforms. The motivation of this setup is to enable mmWave experimentation with a relatively simple system setup. As a demonstration example, we combine the mmWave frontends with the GFDM transceiver to provide a communication link at 26GHz. Moreover, considering mobility, we implement a real-time beam tracking algorithm that switches the beam according to the user’s location. The performance is evaluated in terms throughput, where we demonstrate transmissions up to 3.1Mbits/s.
