IQ Timing Skew (NB-IoT)

IQ Timing Skew is the time difference between the I and Q parts of the signal. This value is calculated for the entire signal in the Measurement Interval.

One possible cause of IQ timing skew is a difference in path length between the I and Q channels within the transmitter circuit.

The Measurement Interval must be longer than one symbol and contain at least one pair of subcarriers that are symmetric about DC for IQ Timing Skew to be calculated.
