Improving the Reliability of 6G Designs with High-fidelity Test Beds

See how CEA-Leti researchers created 6G waveforms using 16-QAM modulation mapped to 4 channels of 2.16 GHz each. Together with modeling, simulation, and signal processing software, they used an AWG70000 Arbitrary Waveform Generator to generate larger than 8 GHz wide baseband signals, which were upconverted to an intermediate frequency of 61.5 GHz. A CEA-Leti TX IC performed channel bonding, did a final up-conversion to 147.96 GHz, and transmitted the signal to the RX IC. The IC down-converted this wide signal and passed it to a DPO70000SX oscilloscope for digitizing and passing of the IQ samples to application software for demodulation.
