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 bandwidth of OFDM?

Each OFDM channel consists of 128 to 2048 sub-carriers and can occupy bandwidths from 1.25 MHz to 20 MHz.
