Demystifying 5G – PAPR: Generating a scrambled payload sequence

Even 5G waveform candidates, such as FBMC, UFMC and GFDM, are based on OFDM, they are pure physical layer concepts that lack of a fully defined scrambling method. This results in a varying peak-to-average power ratio (PAPR) depending on the used payload data which are typically pseudo noise (PN) sequences. In this video we describe how to generate a scrambled bit sequence using the LTE standard.

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