What is OFDM symbol duration?
Figure 1: 802.11n/ac 20 MHz channel—OFDM subcarriers
802.11ax introduces a longer OFDM symbol time of 12.8 μs, which is four times longer than the legacy symbol time of 3.2 μs. Subcarrier spacing is equal to the reciprocal of the symbol time.
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 ...
What is symbol duration?
The symbol duration time, also known as unit interval, can be directly measured as the time between transitions by looking into an eye diagram of an oscilloscope.
How is cyclic prefix duration calculated?
Therefore, the number of samples allocated for cyclic prefix can be calculated as Ncp=Tcp*N/T, where N is the FFT/IFFT length, T is the IFFT/FFT period and Tcp is the duration of cyclic prefix.
