How to calculate number of subcarriers in OFDM?

If you divide the channel bandwidth (20 MHz) by the subcarrier bandwidth (312.5 kHz) you will see that 802.11a/g comprises 64 subcarriers.

How do you calculate OFDM symbol duration?

The duration of your ofdm symbol is Ts=Tt/(N+Ng).

What is the number of subcarriers?

There are K = 64 subcarriers, and the subcarrier spacing is 312.5 kHz. Among the 64 subcarriers, there are 48 active subcarriers modulated by QPSK or 64-QAM constellations.

How many subcarriers are there in OFDM?

A single OFDM symbol contains 52 subcarriers; 48 are data subcarriers and 4 are pilot subcarriers.
