HE Guard Interval Selection (Radio Std 802.11ax)
Specifies the guard interval (also called cyclic extension) length for each symbol
time, as a fraction of the FFT length. The value must match the guard interval length
actually used in the input signal in order for demodulation to work properly. The
value should be between zero and one, and values outside that range are clipped to
be within the range. The value is rounded to the nearest 1/128th. The 802.11ax HE
Guard Interval is for HE part of signal, the Guard Interval of Non-HE part is fixed to
¼. The Auto selection allows to detect 11ax HE Guard Interval automatically.
