6GMADLab professors and researchers revolutionize 5G communications with millimeter-wave phased array prototype and pave the way to 6G
Professors and researchers from the Radiation and Microwave and Radar Groups have developed an FPGA-based hardware platform for the validation and integration of 5G technologies in millimeter-wave bands as part of the DISRADIO project, specifically under the subproject TSI-063000-2021-83: "Desarrollo de tecnologías de sistemas radiantes y subsistemas de RF reconfigurables para futuras redes de comunicaciones en mmWave."
The hardware platform incorporates the implementation of real FR2 5G signals compliant with 3GPP standards, along with the integration of a Phased Array. A phase noise cancellation (PNC) algorithm has been developed and integrated, leveraging phase-tracking reference signals (PT-RS) to jointly compensate for phase noise during reception. The hardware platform has been evaluated in an indoor environment, and a comparative analysis has been conducted between the proposed system and another using horn antennas.
Experimental results demonstrate that the proposed communication system testbed, equipped with the developed phased array, serves as an enabler for 5G/6G by improving KPIs such as EVM, BER, BLER, and throughput. The obtained results have been validated with commercial equipment, showing a close correlation between the measurements and the developed algorithms. The impact of the PNC algorithm on the proposed platform has been explored, revealing significant performance improvements while enhancing data transmission.
