Unwrapped csi phase
Wrapped phase means that all phase points are constrained to the range -180 degrees ≤ Phase Offset < 180 degrees. When the actual phase is outside this range, the phase value is increased or decreased by a multiple of 360 degrees to put the phase value within +/- 180 degrees of the Phase Offset value. For … See more Unwrapped phase lets you designate a point (x-axis) value about which phase values are to be unwrapped. This point is called the Unwrap Reference. This would … See more In a spectrum measurement, the usefulness of phase information is often not obvious.
