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

Full power frequency sweep for 5G PA characterization

This video demonstrates a power vs. frequency sweep while measuring error vector magnitude (EVM), crest factor, adjacent channel leakage power ratio (ACLR) and other relevant parameters using the R&S®SMW200A vector signal generator and R&S®FSW signal and spectrum analyzer from Rohde & Schwarz.

The demystifying 5G video series discusses main topics related to 5G including requirements, timeline, potential frequency and waveform candidates.

Demystifying 5G – PAPR: Scrambled payload sequences for 5G waveform candidates

In this video we explain how to use a scrambled bit sequence as payload in form of a data list for 5G waveform candidates, such as FBMC, UFMC or GFDM, using the R&S®SMW200A vector signal generator.

The R&S®FSW signal and spectrum analyzer downconverts the received signal and provides digitized I/Q samples to an external software tool to calculate channel impulse response and channel transfer function.

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 signal? This video explores this behavior and provides interesting results.
