Abstract
The control unitcalculates weighting factors for one symbol out of every k symbols. During this calculation, the control unitcalculates weighting factors for respective inphase and quadrature components of the symbol stored in every I and Q buffers based on the inphase and quadrature components. The control unitalso interpolates weighting factors for the remaining k-1 symbols. During this interpolation, the control unituses the weighting factors that are currently calculated and the weighting factors that have been previously calculated and are stored in the W buffer. The calculated and interpolated weighting factors are used for forming a directivity pattern.
