Frame Offset (BFN Offset) Calculator

Section 1 : Timing Units

Tc = 0.509 ns
where
Tc = 1 / ( Δfmax x N )
Δfmax = 480kHz // max defined subcarrier spacing
N = 4096 // FFT Size


Ts = 32.55 ns
where
where
Ts = 1 / ( Δfref x N )
Δfref = 15kHz // Reference frequency
N = 2048 // FFT Size

Section 2 : Frame Offset Usage

Frame offset can be applied to shift the start of frame in order to match other operators (to avoid interference) or to have specific combination of vendors with different supported frame structures.
