Demystifying 5G – How about clipping a V5GTF signal?

This video compares the performance of a V5GTF standard-compliant signal showing a standard-dependent high peak-to-average power ratio (PAPR) with a clipped version of such a signal. Did the crest factor improve? How about the error vector magnitude (EVM)?

Demystifying 5G – 5G New Radio (NR) waveform analysis

How to analyze a 5G New Radio (NR) waveform? This video demonstrates how to create a configuration file with the R&S®FS-K96PC OFDM vector signal analysis software from Rohde & Schwarz to analyze an OFDM-based waveform that follows the physical layer parameterization for 5G NR.

Demystifying 5G – US is leading the race for 5G frequency candidates

In July 2016 the Federal Communication Commission (FCC), the US regulator, decided to open up additional spectrum for future 5G wireless communications. This video provides a summary on the intended frequency bands for 5G in the US and explains the potential auction principles.

Demystifying 5G – Where 5G waveform candidates lose their advantage

5G waveform candidates, such as FBMC, UFMC and GFDM, are designed to overcome limitations of LTE. For example, FBMC, UFMC and GFDM outperform LTE in spectral regrowth. Their much sharper power spectrum is a clear advantage over LTE. But what happens, if a non-linear device such as a power amplifier is used to amplify the… Read more »

Demystifying 5G – Full power frequency sweep for 5G PA characterization

5G power amplifiers typically support a power range and a frequency band. It is important to characterize the amplifier for these settings using power and frequency sweep and 5G waveform candidates such as FBMC, UFMC and GFDM. This video demonstrates a power vs. frequency sweep while measuring error vector magnitude (EVM), crest factor, adjacent channel… Read more »

Demystifying 5G – How mobile is 5G at mmWave frequencies?

mmWave frequencies provide quite some challenges, including a much higher Doppler shift compared to sub-6 GHz frequencies when targeting higher speeds. This puts some significant challenges on system design to enable full mobility. In this video we explore the fundamentals for mobility in a cellular system and show how (pre-)5G and 5G systems eventually tackle… Read more »
