What are symbols in OFDM?

Orthogonal frequency division multiplexing (OFDM) takes a digital information signal with bit rate Rb, maps n-bit words on to M = 2n symbols (each symbol being a complex number representing the amplitude and phase of an M-ary modulation scheme), splits the resulting symbol stream (rate Rs = Rb/n) into N parallel ...

How many OFDM symbols are there?

The number of OFDM symbols per slot is 14 for a configuration using normal cyclic prefix. For extended cyclic prefix, the number of OFDM symbols per slot is 12.

What is OFDM symbol period?

Each OFDM subcarrier is 312.5 KHz. Figure 1: 802.11n/ac 20 MHz channel—OFDM subcarriers. 802.11ax introduces a longer OFDM symbol time of 12.8 μs, which is four times longer than the legacy symbol time of 3.2 μs.

What is OFDM symbol in 5G?

Orthogonal Frequency Division Multiplexing (OFDM) is an efficient modulation format used in modern wireless communication systems including 5G.
