WebMar 1, 2024 · The big advantage of OFDM is low complexity at the receiver. A single DFT plus one-tap equalization is sufficient for the detection. In contrast, VOFDM requires additional M-point DFTs on each carrier to perform one-tap equalization. In OFDM, each frequency bin can be treated independent from the others (it's orthogonal). WebDFT-s-OFDM (DFT spread OFDM) You would know of SC-OFDM because this is the waveform that we use in current LTE. If you are familiar with SC-FDMA, you can easily understand DFT-s-OFDM. High level view of DFT …
WebDFT-spread OFDM (DFTS-OFDM) is a transmission scheme that can combine the desired properties for uplink transmission i.e.; small variations in the instantaneous power of the transmitted signal (‗single carrier‘ property), possibility for low-complexity high-quality equalization in the frequency domain, possibility for
WebThis waveform is also referred to as single-carrier FDM waveform (SCFDM) in the literature. In 3GPP 5G NR, QAM modulation symbols with modulation order (4, 16, 64, 256) can be transmitted using the DFT-s-OFDM. When compared to LTE, a new modulation scheme, namely, π 2 -BPSK was introduced in 5G NR. This is a special constellation-rotated …
