Granular guard interval tuning
Granular guard interval tuning may be provided. A delay profile for a plurality of sub-bands in a serving channel may be created. Then delay spread information from at least one calibration helper device for the plurality of sub-bands in the serving channel may be received. Next, a delay spread matrix based on the delay profile, the delay spread information, and a location of the calibration helper devices may be created. The delay spread matrix may then be used to determine optimal Guard Intervals (GIs).
