the upcoming sixth generation (6g) of mobile communication systems is expected to push technological boundaries by enabling ultra-high data rates and extremely low latency. it aims to support a wide range of innovative use cases, typically categorized into four domains: network-enabled robotics and autonomous systems, multisensory extended reality, integrated sensing and communications, and personalized user experiences. among the various promising enablers, sub-thz communications have emerged as a technology candidate for the 6g and beyond era, offering the potential for terabit-per-second data rates to meet the extreme performance demands of these applications. to realize this vision, operation in sub-thz frequency bands is part of ongoing research projects.

this application note presents a practical approach to generate sub-thz communication signals for 6g based on using dft-s-ofdm (discrete fourier transform spread ofdm) modulation. the implementation is realized on a flexible, gui-controlled testbed built with rohde & schwarz instruments, including the sfi100a vector signal generator, fsw signal and spectrum analyzer and external rf frontends.

a custom-built graphical user interface (gui) coordinates all equipment and enables rapid prototyping of communication signal configurations, control of signal generation and measurement automation.

this application note serves as a guide for researchers and engineers looking to evaluate or generate future communication signals in the sub-thz domain using commercial measurement equipment.
