What is CP-OFDM and DFT's OFDM?
The CP-OFDM waveform can be used for either single-stream and multi-stream (i.e. MIMO) transmissions, while DFT-S-OFDM based waveform is limited to single stream transmissions by targeting scenarios with limited link budget. Physical Channel Bandwidth.
What is DFT s OFDM in 5G?
Abstract—DFT-s-OFDM/Discrete Fourier Transform (DFT) spread Orthogonal Frequency Division Multiplexing (OFDM) is a waveform adopted in the forth and fifth generation of the mobile communication standards, aiming to combine the merits of Cyclic Prefix (CP) OFDM with a low Peak-to-Average-Power Ratio (PAPR).
What is Dfts OFDM?
The DFT-spread OFDM is a form of single-carrier technique that possesses almost all advantages of the multicarrier OFDM technique (such as high spectral efficiency, flexible bandwidth allocation, low sampling rate, and low-complexity equalization).
What is CP-OFDM 5G?
CP-OFDM is used as the access technology for 5G New Radio. Its operation is very similar to that of OFDM used in LTE, however CP-OFDM features variable subcarrier spacing termed “numerology”. Where LTE uses a fixed 15kHz subcarrier separation, CP-OFDM can utilize 15kHz, 30kHz, 60kHz, 120kHz, etc.
