Demystifying 5G – PAPR: Difference for 5G PHY layer concepts vs. LTE

The peak-to-average power ratio (PAPR) is a critical parameter for describing a waveform, such as OFDM. 5G waveform candidates, such as FBMC, UFMC and GFDM, are also OFDM-based. In this video we explore the PAPR for these waveforms and compare them to LTE, a fully standardized technology including scrambling and channel coding methods. FBMC, UFMC and GFDM are pure physical layer concepts and thus lack of a fully defined scrambling method. How this fact impacts the PAPR for the 5G waveform candidates is also analyzed.

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