How DFT-s-OFDM helps in reducing PAPR (Peak to Average Power Ratio)
Просмотров 5 тыс.3 года назад
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 ...
PTRS in 5G NR | Saviour from Phase Noise for mmWave 5G NR
Просмотров 3,4 тыс.3 года назад
5G Millimeter wave (mmWave) bands can offer much larger available spectrum bandwidth and thus are considered as one of the most promising approaches to significantly boost the capacity in 5G NR. However, devices and network radio nodes operating on mmWave bands suffer from phase noise and without correction of phase noise, the performance of the network could potentially suffer significant loss...
