Summary:
Although 5G millimeter-wave (mmWave) communication systems enable high-speed and large-capacity communication, the deterioration of communication quality due to path blockage is one of the challenges that should be addressed. This work studies the realization of multipoint coordinated robust beamforming on an experimental platform composed of off-the-shelf computing devices and developed prototypes of hybrid beamformers to overcome inherent instability due to random blockage and verify its performance. Robust beamforming algorithms are implemented on open-source software, OpenAirInterface, which is compliant with 3GPP. The details of the implementation and architecture are presented. Through our experiments, we confirm that user equipment can achieve high throughput stably, even in environments with random blockages.
