How DFT-s-OFDM helps in reducing PAPR (Peak to Average Power Ratio)?

Hi Experts,

OFDM has many advantages but few disadvantages also. One of them is high PAPR (Peak to Average Power Ratio). In cellular communication technologies like 5G NR and LTE, DFT s OFDM is used for low PAPR applications.

This video explains the framework of DFT-s-OFDM, different subcarrier mapping techniques, simulations results for PAPR and the analytical comparison between OFDM and DFT-s-OFDM using a simple example.
