obtain frequency of the ofdm subcarriers in 802.11n

[cpy]

In 802.11n, we can get the channel state information(csi) from the 802.11n frames. However, the csi just contains the phase and amplitude of the subcarriers in ofdm. Now, I want to get the corresponding frequency of each subcarriers. How can I obtain them? Through some searching, I know I have to get the frequency spacing and the frequency range(or starting frequency) to calculate it. But how can I get these two values? Is the 802.11n frequency range different in a different country or regions?

Hello
I want to ask you friend what is the NCBPS(number of coded bit per symbol) and how we can get it if we have Ndsc(number data subcarrier)=100;and code rate 1/2;and QPSK Modulation
Regards,

@Big.Head. sorry, I know little about that. So I can't help you.

The frequency spacing is one of the most important parameters that define a particular OFDM standard.
For Wi-Fi there are 52 subcarriers (48 for data and 4 for pilots) spaced by 312.5 kHz
The channel used (i.e. starting frequency) varies for each particular LAN (spot).

So, does it mean that if i want to get the frequency of the subcarriers in 802.11n, I should use the frequency spacing 312.5kHz and the starting frequency of my LAN to calculate it? I'm not sure whether this method is right. Or there are other general methods?
