OFDM Symbol Timing Calculator

Turn a sample rate, FFT size and cyclic prefix into the timing and bandwidth of each OFDM symbol.

MS/s (million samples per second), 0.001–1000
total useful-symbol samples
prefix samples ÷ FFT size
used for occupied-bandwidth estimate; 1–FFT size

—Enter the symbol settings above.

Uses uniformly spaced subcarriers and a prefix copied from the end of the useful symbol. Occupied bandwidth is active subcarriers × subcarrier spacing; guard-band and spectral-mask requirements are not modelled.
