ABSTRACT:
The control unit50calculates weighting factors for one symbol out of every k symbols. During this calculation, the control unit50calculates 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 unit50also interpolates weighting factors for the remaining k-1 symbols. During this interpolation, the control unit50uses the weighting factors that are currently calculated and the weighting factors that have been previously calculated and are stored in the W buffer51. The calculated and interpolated weighting factors are used for forming a directivity pattern.
