“…The base-3 structure uses, like the redundant CORDIC, the possibilities of a rotation by 0 • and, hence, it rotates either +α, 0, or −α. However, contrary to the redundant CORDIC, by using the coefficient scaling method [2], the scaling error can be considered in the selection of the coefficients. This assures a uniform scaling, i.e., the same gain for all angles.…”
