Conchi García Pardo and César Montaner, researchers from the Mobile Communications Group (MCG) at the Institute of Telecommunications and Multimedia Applications (iTEAM) of the Universitat Politècnica de València (UPV), recently took part in the European COST programme meeting held in Lille, France.
During the event, Conchi García Pardo, as chair of one of the working groups, leads technical and strategic discussions focused on the current impact of 5G mobile communication systems on electromagnetic fields levels. It was shown that even in cases of maximum capacity, those systems always operate in safety conditions. Besides, the working group led by Dr. Garcia-Pardo analyzed the role of 6G radio strategies on the future levels of electromagnetic fields.
Meanwhile, César Montaner presented a talk on an innovative algorithm for channel matrix compression in Massive and Gigantic MIMO systems. In his presentation, Montaner explained the operation of this new algorithm, designed to reduce the dimensionality of channel matrices while preserving the essential properties of the original system. He compared his approach with other compression methods, such as Singular Value Decomposition (SVD), using correlation metrics, mean squared error over the channel’s IFFT, and system capacity.
The results showed that the algorithm preserves the fidelity of the original matrices while significantly reducing their size, which could have a major impact on channel dataset generation, Digital Twin development, and the training of artificial intelligence and machine learning (AI/ML) models. By decreasing the amount of data required for storage and training, the method also achieves a notable reduction in computational cost.
