Thus the bandwidth of the OFDM baseband signal is N/2*delta_f,delta_f is the sub-carrier frequency spacing. The sub-carrier frequency spacing delta_f =1/Ts= 1/(Td * N), Ts is the OFDM symbol duration,Td is the sampling symbol duration and equal to the smapling time interval。 Thus Td=1/fs, fs is the DAC sampling rate.

How do you calculate the number of OFDM symbols?
WiMAX MAC Frame To calculate total number of OFDM symbols transmitted per frame, first we have to calculate OFDM symbol duration which is given as: TD OFDM = useful symbol time + guard time TD OFDM = useful symbol time + G * useful symbol time TD OFDM = [1 / (f s / N FTT )] * (1 + G)-(1) Where N FTT is total number of ...
How do you calculate OFDM symbol duration?
The duration of your ofdm symbol is Ts=Tt/(N+Ng).
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 bandwidth from symbol rate?
C(bps) = 2B * log2M (Nyquist)
C is the capacity in bits per second, B is the frequency bandwidth in Hertz, and M is the number of levels a single symbol can take on. This "idealized" capacity equation shows us that data rate is proportional to twice the bandwidth and logarithmically proportional to M.
