The main benefit of OFDM over single-carrier schemes is its ability to cope with severe channel conditions without complex equalization filters . It has improved the quality of long-distance communication by eliminating InterSymbol Interference (ISI) and improving Signal-to-Noise ratio (SNR).
Read moreWhy there is need of OFDM role of OFDM in 5G?
5G Cellular Technology Tutorial Includes: OFDM gives good spectral efficiency whilst providing resilience to selective fading and it also enables multiple access capability to be implemented using OFDMA .
Read moreDoes 5G use SC FDMA?
Unlike LTE, 5G NR also supports CP-OFDM in the uplink direction. But LTE’s discrete Fourier transform spread OFDM (DFT-s-OFDM) uplink scheme, better known as single carrier frequency division multiplex (SC-FDMA), is still a valid access scheme and support is mandatory for any 5G terminal.
Read moreWhat is OFDM what are its advantages and application?
The main advantage of OFDM over single-carrier schemes is its ability to cope with severe channel conditions (for example, attenuation of high frequencies in a long copper wire, narrowband interference and frequency-selective fading due to multipath) without the need for complex equalization filters.
Read moreWhy OFDM is used in LTE?
Using multiple carriers, each carrying a low data rate, OFDM is ideal for high speed data transmission because it provides resilience against narrow band fading that occurs as a result of reflections and the general propagation properties at these frequencies .
Read moreDoes WiFi use OFDM?
802.11a/g/n/ac radios currently use Orthogonal Frequency Division Multiplexing (OFDM) for single-user transmissions on an 802.11 frequency .
Read moreIs OFDM a modulation?
OFDM in its primary form is considered as a digital modulation technique , and not a multi-user channel access method, since it is used for transferring one bit stream over one communication channel using one sequence of OFDM symbols.
