the coefficients in Equation (28-22) to Equation (28-31) are set to zero if those values are corresponding to tone indices that fall within RUs that have no users assigned to them." Please provide analysis that not assigning values to tone indices with blank RU's will not degrade correlation performance, as there will effectively be a different sequence/pattern for each combination of blank RU's. Do all sequences have good correlation properties? The main purpose of the HE-STF is to improve automatic gain control estimation in a MIMO transmission.
