摘要
A CORDIC processor is configured to perform orthogonal or oblique CORDIC projections in order to cancel interference in a received signal. The CORDIC projection can be used to rotate an interference signal vector so that its only non-zero component is in the last Euclidean coordinate of the representative vector. A measurement vector is then subject to the same rotations as the interference vector. As a result of the rotation on the measurement vector, all components of the measurement vector parallel to the interference vector will be resolved onto the same coordinate as the rotated interference vector. The parallel components of the symbol vector can be cancelled by zeroing that coordinate, and the modified measurement vector can then be rotated back to its original coordinates, to produce an orthogonally projected version of the original measurement vector. Typically, the projection is onto a subspace that is orthogonal or oblique to an interference subspace, which may be one-dimensional.
