How Is The Data Rate Calculated In Fixed Wimax Based On Ofdm Physical Layer?

Answer»

Data rate is the rate at which data is transmitted over the air and is MEASURED in Mbps.
Raw data rate = Nsc * bm * Cr /Ts;
Where Nsc is the number of data subcarriers(here 192 for OFDM),
bm is CODED bits per sub-carriers
Cr is ratio of input bits to output coded bits
Ts is the symbol duration 
For BPSK 1/2, Maximum data rate will be (192*1*1/2)/(11.8 microsec) = 8.13 Mbps.
For 64QAM 3/4, Maximum data rate will be (192 * 6 * 3/4)/(11.8) =73.2 Mbps.
