As 5G standards are realized, the goals for higher data rates, lower-latency network access, and more energy-efficient implementations are clear, according to Rick Gentile, product manager, Phased Array System Toolbox and Signal Processing Toolbox, Math Works. "How do you build a cost-effective system that achieves all of these goals?" he asks. "We know that higher data rates drive the need for greater bandwidth spectrums, which moves operating frequency bands up into the millimeter-wave range. This creates new challenges in understanding complexities in the propagation channels. We also know that all of the subsystems, from the antenna, through the RF chain, to signal processing, have to be active parts of the system-level solution. These subsystems each contain design 'knobs' that can be tuned together to meet system design goals." In an email Q&A, he elaborates on hybrid beamforming and its applicability to the implementation of mm Wave 5G technology.
